Chromium - slow in 'textarea', 'input'

pszafer · 2015-09-11 12:40:07

Hello,

From last Monday I have problem with Chromium, inputting text in text boxes in websites is very very slow.
Even here, when I'm writing this text, I have to use gedit and paste it later, because letter appear with about one second delay.

I'm using 'Profile-sync-daemon', the newest 'Chromium', but in my opinion it is something with my graphic card driver.
My PC is Asus N56VZ.
Where can I look for some logs why this delay occurs? Do you have any idea?

Thank in advance for help!

1. For logs: Try running Chromium from a terminal, you might get some output.
2. Try a fresh Chromium profile. Backup and delete the entire folder. You could also try a new system user, to make sure it's not some configuration problem.
3. Try eliminating the sync daemon as the culprit.

Why would you suspect that? That seems completely out of no where.

Have you tried other browsers, or other versions of the browser?

If you really think it is your graphic driver, it would be wise to tell us what graphic driver you are using. And have you tried an alternative driver?

I'm having the same issue too, I think it might be something graphics related too since it persists across profile deletion, removal of all addons, across desktop environments.

In my case I get lag:
- On typing in the omnibar
- Switching between tabs
- Rendering after opening more and more tabs

The chromium resource manager shows 100% CPU usage from the Chromium browser

EDIT:
Disabling/Enabling hardware acceleration doesn't seem to have much of an effect.
I also have the same problems with google-chrome-stable (hence my suspicion of a graphical issue)

I've been poking around and removing all my ~/.* files has caused the problem to disappear even after reinstalling all my addons etc, now I just have to figure out which one is causing it.

EDIT: OK, so it's something inside the ~/.config folder causing it as moving it away removes the problem.

EDIT2: Seems to be ~/.config/fontconfig

I can say for sure, that in my case after reboot the laptop everything is ok.
After writing a few mails or something in input boxes lag is back

What I can say that:
- I have kernel module driver i915

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) (prog-if 00 [VGA controller])
	Subsystem: ASUSTeK Computer Inc. N56VZ
	Flags: bus master, fast devsel, latency 0, IRQ 30
	Memory at f7400000 (64-bit, non-prefetchable) [size=4M]
	Memory at d0000000 (64-bit, prefetchable) [size=256M]
	I/O ports at f000 [size=64]
	Expansion ROM at <unassigned> [disabled]
	Capabilities: <access denied>
	Kernel driver in use: i915
	Kernel modules: i915

For sure I know second laptop with i915 module loaded has the same lag as I have.
But I have third laptop with Arch installed and this one doesn't have any lag.

I've check will.prive94 solution, but I don't such path ~/.config/fontconfig so in my case this is not a problem.
I'll remove profiles of chromium and try to check that.

I have discrete card Nvidia, and with lspci -v I have output:

01:00.0 VGA compatible controller: NVIDIA Corporation GK107M [GeForce GT 650M] (rev ff) (prog-if ff)
        !!! Unknown header type 7f
        Kernel modules: nouveau, nvidia

I can run

modprobe nvidia

and for short time I have output, which I think is correct:

01:00.0 VGA compatible controller: NVIDIA Corporation GK107M [GeForce GT 650M] (rev a1) (prog-if 00 [VGA controller])
        Subsystem: ASUSTeK Computer Inc. N56VZ
        Flags: bus master, fast devsel, latency 0, IRQ 16
        Memory at f6000000 (32-bit, non-prefetchable) [size=16M]
        Memory at e0000000 (64-bit, prefetchable) [size=256M]
        Memory at f0000000 (64-bit, prefetchable) [size=32M]
        I/O ports at e000 [size=128]
        [virtual] Expansion ROM at f7000000 [disabled] [size=512K]
        Capabilities: <access denied>
        Kernel driver in use: nvidia
        Kernel modules: nouveau, nvidia

My problem is, that I really haven't idea if this problem occurs same time as chromium lag or it was there before

EDIT2: I found that thread: https://www.reddit.com/r/archlinux/comm … input_lag/
and switching Intel card from SNA to UXA https://wiki.archlinux.org/index.php/In … SNA_issues seems to resolved the problem after all.

For almost half an hour everything is working now
