Chromium is intermittently very choppy

I've been using the same setup for roughly 3 years now (no re-installs in between) and for the most part everything has been smooth, up until about 2 or 3 days ago, where Chromium at seemingly random moments becomes very choppy to use, whether I'm watching a video, scrolling through a very basic web page of mostly just text, or even adjusting the cursor when writing this.  Eventually, it runs butter smooth like it used to, but a few seconds later and it's back to being choppy again.  Neither CPU nor GPU usage tends to get beyond 15% whenever this choppiness occurs.  It's as though Chromium is actually running just fine, but it isn't rendering all the frames.  During this slowdown, other programs remain perfectly smooth.

I tried clearing the browser cache, which didn't help.  According to "chrome://gpu", all of the graphics features are enabled/accelerated except for "CheckerImaging" and "Native GpuMemoryBuffers", which to my recollection, neither of them were ever accelerated.  On the same page, the log at the bottom has a lot of entries that look like this:

[824:824:0524/212444.974817:ERROR:sync_control_vsync_provider.cc(141)] : Calculated bogus refresh interval=0.153693 s, last_timebase_=127198534 bogo-microseconds, timebase=127352227 bogo-microseconds, last_media_stream_counter_=478, media_stream_counter=479

Here's my setup:
Haswell i3 using Intel graphics
KDE + Wayland + OpenGL 3.1 compositor
Chromium 66.0.3359.181
Mesa 18.0.4-1

I also tried installing Chrome from the AUR, which didn't help.

Re: Chromium is intermittently very choppy

Hi @schmidtbag, I wonder if this is the same issue as I am experiencing: https://bbs.archlinux.org/viewtopic.php?id=237389.

Have you tried other browsers, e.g. firefox or epiphany? Epiphany is interesting because it has support for Wayland. Is chromium running through XWayland for you? Have you tried running the same thing on Xorg?

Edit: I closed/merged my post above and copied it here. Also, maybe you could edit title of the post to mention this is happening on Wayland?

Re: Chromium is intermittently very choppy

Hi, I seem to have very similar or same issue so let me explain it.

I did a fresh install of Arch on new laptop and am experiencing tearing / glitches when using Google Chrome in Gnome on Wayland.
Specifically, scrolling is not as smooth as it normally is, it is blocky / tearing. It gets better when I scroll few times through the same content, as if rendering of fresh content is causing problem. Similar is with opening or closing a tab, animation of tab itself at the top of the screen is not smooth. In general, whole experience is like that, but these are the details I identified.

Tests I did:

  1. I tried running chromium in Gnome on Wayland, same problems.

  2. I tried running epiphany in Gnome on Wayland, it works fine.

  3. I tried running Google Chrome in Gnome on Xorg, and there are no problems then, everything is smooth. For this test I just logged out from Wayland and logged into Gnome on Xorg.

Google chrome complains about fonts when run in terminal, chromium is quiet, so I don't think that is a source of this problem.
I checked windows with Gnome Looking Glass and I can see that Google Chrome and Chromium are running on XWayland, while Epiphany is running on Wayland.
From this, I am assuming that problem is probably connected to Google Chrome / Chromium running on XWayland.

I also read that Google Chrome supports Wayland since version 50 so I wonder why is my version of Google Chrome, which is much later, not running on Wayland but on XWayland, therefore on Xorg? Or is that information incorrect?

I have no experimental features or extensions running in Gnome, it is freshly installed.

I am using Gnome on Wayland because I normally have two external displays connected, each 2K resolution, and Gnome with Wayland is the only one that has actual scaling (not just font scaling) that can be separately set for different displays, plus it has fractional scaling (still experimental but kind of works, although some stuff is blurry. But I got much worse results with xrandr scaling, a lot tearing, so I am sticking with Gnome/Wayland. I turned it off for tests). On my old laptop I was using XFCE with font scaling.

Detailed context info:
  Machine: Dell XPS 15, 9560, 4K internal screen, 32GB RAM, 1TB SSD, discrete Nvidia GPU, integrated Intel Video card.
  Kernel: 4.16.9-1-ARCH, options: acpi_rev_override=1 acpi_osi=! acpi_osi='Windows 2015'. I need first one for basic stuff to work, next two I need for bbswitch to not freeze everything on boot.
  Bootloader: GRUB, and I also have intel-ucode.
  Video: I have bumblebee + bbswitch, they work fine. Drivers are `nvidia` (when bbswitch is on) and i915 otherwise. I dont have xf86-intel-video installed. I do have nouveau still installed, but it is not visible in dmesg and since `nvidia` package is blacklisting it. During tests above I confirmed that they are running on integrated intel video card.
  Versions:
    gnome: 3.28.2-1
    google-chrome: 66.0.3359.181-1
    chromium: same as google-chrome
    nvidia: 396.24-3
    wayland: 1.15.0-1
    bumblebee: 3.2.1-17
    bbswitch: 0.8-135

Additional:
I get this funny (but annoying) behaviour with touchpad: if I touch it with slightly moving motion (which is normally how I do it) after not touching it for a few seconds, mouse jumps in the corresponding correction for a significant portion of the screen (20% to 50%). This sometimes moves mouse pretty far away from what I wanted. It is as if it calculates the impact of my finger with touchpad and responds to that, making it jump proportionally. If I approach it very very gently, it is fine. This happens both on Wayland and Xorg. When using mouse, everything is fine.
Should I open special post for this?

Here is link to html of chrome://gpu since it is much easier to read: https://drive.google.com/open?id=1_PA1G … eyZdD5KAai .

Important fact here is that I also have those logs about vsync errors.

I took same report from Chrome on Gnome + Xorg, where it works fine:

Main difference on Xorg is that there are no log messages about error with vsync, so I am guessing that is probably directly connected with the problems we are having!

Re: Chromium is intermittently very choppy

I will be closing this one due to merging it with another post that is talking about the same issue: https://bbs.archlinux.org/viewtopic.php?id=237383 . -> this is leftover from merging topics.

Re: Chromium is intermittently very choppy

I actually am not experiencing tearing issues.  To my knowledge, Chromium is and has been running in Wayland natively for a while now.

Re: Chromium is intermittently very choppy

Maybe I am calling it wrong name -> it is certainly choppy and not smooth as it should be. I am pretty sure it is the same thing since we are getting same error. It is not even that easy to notice, I see that stuff is not smooth but it is not super clear why. I even thought at some moment I am going crazy, I guess I got more used to it, but then I switched to xorg and difference was obvious.

Can you somehow confirm that Chromium is running on Wayland natively for you? I used Looking Glass on Gnome and I can confirm in my case both Google Chrome and Chromium are running on XWayland.

Re: Chromium is intermittently very choppy

For me, the choppiness is VERY apparent.  Like I said, my problem is intermittent - sometimes I can scroll around the page and it is perfectly smooth.

I won't be at my PC with the problem until later tonight so I can't currently confirm if it is running in Wayland natively, but I'm 90% sure it is.  Regardless, I will intentionally run it in XWayland and see if that changes the behavior.

Re: Chromium is intermittently very choppy

I still wonder if we are talking about the same thing or not hm smile! But, what we can do is go about figuring out the facts, so looking forward to results of your tests. Btw., how do you intentionally run smt on XWayland if it is Wayland native?

Re: Chromium is intermittently very choppy

Honestly, I'm pretty sure we're not, but we still may be able to help each other out anyway.  Chromium for me goes from running very smooth to frustratingly slow, all without having any effect on CPU or GPU usage.

To answer your question:

GDK_BACKEND=x11 chromium

Re: Chromium is intermittently very choppy

So - I have confirmed that Chromium is currently not running in native Wayland like I thought it was.  An easy way for me to test this is with middle-click paste, which only works in XWayland applications.  I'm now looking into why it isn't running in Wayland, because I'm pretty sure I have been for over a year now, and this would make a lot of sense as to why I'm getting these performance issues.

EDIT:
Even if I try to run Chromium in Wayland, I can't (using "GDK_BACKEND wayland").

EDIT 2:
I tried downgrading a couple versions.  I'm not sure if it's any better or not, but it's still pretty bad.  I'm beginning to question if I have ever ran Chromium in Wayland at this point.

Either way, still doesn't explain why it is running so slow at such random times.

Re: Chromium is intermittently very choppy

If you can try Atom or VSCode or other Electron based program and see flicker too, I think you are suffering the same issue as mine.

If you are using xorg-server 1.20 and xorg-server-xwayland 1.20, you can downgrade them to 1.19, which fixed my issue.

Re: Chromium is intermittently very choppy

Good find AlynxZhou! Chromium runs almost as smooth as it does in native X11 (I tried booting in X11 instead of Wayland to see if it fixed the problem, and it did).  The stream of errors found in chrome://gpu went away, too.

I forgot to downgrade xorg-server-xwayland and the problem seems to remain fixed.  Downgrading xorg-server required the Intel drivers to be downgraded along with them.

Seems this bug is specific to Xwayland, but, it doesn't appear to be specific to the xorg-server-xwayland package.

Re: Chromium is intermittently very choppy

I'm getting the same problem as well in all the Chromium based browsers I use. You could also try disabling HW acceleration in Chromium settings if you need to have the latest x-server.

Re: Chromium is intermittently very choppy

Yeah I tried disabling HW acceleration too.  It helped, but not enough.  Since I'm using a laptop with an i3, going full-software botttlenecks my CPU pretty quick.

Re: Chromium is intermittently very choppy

Nice, so it seems @schmidtbag that you managed to confirm the same conditions that I described in my posts.
I tried running Atom, is also does not work as smooth as it should, although it is not as bad as Chromium.

To revise, what we know so far:
- Running Chromium on Wayland (Gnome, KDE) runs it through XWayland.
- Running Chromium through XWayland makes it perform poorly.
- Chroimum works fine on Xorg.
- If we downgrade xorg-server from 1.20 to 1.19, Chromium works fine on XWayland. But we don't have to downgrade xorg-server-wayland.

I wonder what is the problem, and can we achieve smt without downgrading? Also, we should report this error/bug somewhere so they fix it. I am not sure where to report it in this case?
@Alynx Zhou have you reported the problem anywhere?

Re: Chromium is intermittently very choppy

I looked through all of the noteworthy changes of Xorg server 1.20, and I found one thing that especially stood out to me: multi-buffered Xwayland support.  The errors I'm getting in Chromium are related to vysnc, so I wonder if Xwayland's buffers are causing some sort of conflict.  After all, vsync is just a form of buffering.

I'll keep looking into it, but if anybody knows a way to disable multi-buffering, that might be all we need.

EDIT:
Just a side note for Martinsos - if you're using KDE, why don't you use KATE instead of Atom?  It offers pretty much all of the same features (most of which are built-in), it's easier to use, it's more polished, it uses fewer system resources (only if you're using KDE), and it works natively with Wayland.  Due to the smaller userbase, there aren't quite as many features, but I find a lot of those smaller ones easy to give up.  I personally use both (I use Atom at work, where I'm using XFCE and don't want to deal with hundreds of MB of KDE dependencies).

Re: Chromium is intermittently very choppy

Should help as a temporary solution:

--disable-gpu-vsync=gpu

Re: Chromium is intermittently very choppy

There is another solution I used and it works 

--disable-gpu-driver-bug-workarounds

Since most workarounds are too old and have long been solved.
But it is better to highlight specific workarounds for shutdown than all at once.

Re: Chromium is intermittently very choppy

Since Chromium is working fine when run directly on xorg server, and it does not work fine when run on xwayland, I am guessing that the real problem is in xwayland? Maybe multi buffering update in xorg-server is causing problems with xwayland and they have to fix it there? I will consider posting a bug to xwayland then.

@surefire: Thanks for the temporary solution! Where would I set that flag if I am running Chromium on xwayland?

@schmidtbag: Thanks for the tip! However I am not using KDE, I have been using XFCE in the past and now Gnome (due to it's HiDPI support). For my main editor I am actually using Emacs (mostly for C/C++, Python). I use Atom only for Javascript development, because support in Emacs is still not good enough for JSX unfortunately, I guess because not so many JS developers are using Emacs.

I also have noticed laggy graphics in google-chrome (AUR) recently on GNOME Wayland but adding the above flag fixes the issue for me, thanks.

I am planning to open a issue to primus because it fails with xorg 1.20, but I have no idea with chromium.

Maybe there is a bug when passing data in xwayland? But it seems that downgrade xserver fix the bug, not xwayland...
