Re: Stutters in Xfce with vulkan app launched

Did you compare "glxinfo -B" between the environments and maybe "printenv" to see whether KDE sets some environment that results in defaulting to the other GPU or might otherwise have a performance impact?

Difference in memory usage, also the display names are different: in KDE it's just 0, in xfce4 it's 0.0

Provided a link to git gist with logs and env output for xfce4 and KDE in the first post.
The files with env output have the “_enviroment” postfix.
Here it is:
https://gist.github.com/QTaKs/f57dd2a9c … 54de354b54
Seems to me the only difference is the internal DE variables

Re: Stutters in Xfce with vulkan app launched

Remove all the __GL* variables and vblank_mode and mesa_glthreaded and MESA_WHICH_LLVM - the "KDE" environment is likely some konsole output and you're probably setting at least some of that w/ your shell RC, but KDE starts as systemd user services.
This screams double-syncing.

Re: Stutters in Xfce with vulkan app launched

MESA_WHICH_LLVM is only used when building aur mesa-git and in #5 OP stated they had tried to build that but didn't succeed ..

Removing it should not matter, but also bring no harm.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

In order to see if my settings are affecting the stuttering, I did some tests on a “clean system” - a LiveCD created with archiso.
The last tests with Gnome, Xfce4, Enlightment and KDE I ran in it.
All these variables in the LiveCD are supposed to be in default positions, so I don't think my settings specifically affect stuttering.
But I'll remove the variables just to be sure.

Re: Stutters in Xfce with vulkan app launched

I removed it and tested it, as the results of testing in LiveCD showed - nothing changed, stutters are still there, the variables didn't affect them.

Re: Stutters in Xfce with vulkan app launched

So it's not the Display server, not the compositor, not the environment, not the power profiles/performance mode… and still.

Do both stutter or just one of them ?

vkcube on igpu - no stutters

vkcube on dgpu - less frequent than usual, but there are

We didn't pick up on thise, did we?
If you force VK_DRIVER_FILES to run on the nvidia GPU in the KDE context, do you get stutter?
If you force VK_DRIVER_FILES to run on the amdgpu GPU in the XFCE context, do you get stutter?
When the system "stutters", is there abnormal CPU load?
If you run "sudo journalctl -f", does the stutter come along journal error spam?

No, why? I checked.
For this test, as Lone_Wolf advised, I started everything in twm via startx (using default xinitrc).
Vkcube runs on nvidia dgpu by default, so I used a variable to run on igpu.
You saw the results of the test.

Strange, I remember that I wrote conditions of stuttering, but I can't find them in the topic, so I'll duplicate:
one monitor to igpu, another to dgpu (that is Reverse PRIME setup), Xorg on igpu, vulkan-application runs (offload) on dgpu.
For tests, I use vkcube (by default runs on nvidia dgpu) as vulkan application and LibreOffice Draw (igpu) to provoke stuttering.

Accordingly, if you run everything on igpu or dgpu - no stutters.
Exactly in the situation I described above (Reverse PRIME) there are no stutters only in KDE and wayland compositors.

seth wrote:

Yes, there is. One or two cores are loaded at 100% exactly for the duration of the stutter.

seth wrote:

No, journalctl -f doesn't show anything.
Again, you can look in git gist for files with the postfix “_journalctl_b”, my attempts to cause stuttering at the very end of those files - no trace of errors.
The stutters only show up in the Xorg logs, as I wrote in the first post. (Xorg logs have the postfix “_Xorg_log ”).

Perhaps I should have uploaded the logs to another resource, as it turns out git gist is not the most convenient service for this.

Also on KDE when there's no stutter but you'd expect it?
(Ie. is that context simply better at handling the CPU overload or does it avoid it)

Also: what process hogs the CPU?

No, in KDE the load graph is “flat” with no spikes.

Judging by the info from top - Xorg, it raises usage to 100% for the duration of the stutter, then goes down.

The output of

Re: Stutters in Xfce with vulkan app launched

Xorg, it raises usage to 100% for the duration of the stutter, then goes down.

So the Xorg CPU usage  becomes the bottleneck and

No, in KDE the load graph is “flat” with no spikes.

that doesn't happen in KDE.
At least we now know what causes the stutter.

What if you enable triple buffering?

Section "Device"
        Identifier "NVIDIA Card"
        Driver     "nvidia"
        Option         "TripleBuffer" "on"
EndSection

Checked, the stuttering remains.
I checked that the option is enabled in Xorg.log

Re: Stutters in Xfce with vulkan app launched

https://forums.developer.nvidia.com/t/h … 119?page=2 - seems a common issue.
Though the oddity remains that it does not happen in KDE and it's not because of the kwin_x11 compositor (as that doesn't prevent the issue in an xfce session, otherwise I'd have said the vsync rate-controls the load)
…
…
…

grep -iC5 plasma /usr/share/drirc.d/00-mesa-defaults.conf

startplasma disables adaptive_sync… what if you "export adaptive_sync=false" to whatever session you're gonna try?
It's disabled for picom and xfwm4, but I wonder whether startplasma makes it leak into the entire session…

Unfortunately, it didn't help.
vkcube at startup displays a notification that “default value of option adaptive_sync overridden by environment”, so definitely applied.

I also checked the output of 

xdriinfo options radeonsi

for xfce4, kde and lxqt - identical.
