Most graphics broken on Chromium on AMD laptop; Skia, shader errors

After updating with pacman -Syu a few hours ago, Chromium stopped displaying most graphics. It produces lots of errors in its terminal, seemingly including entire shaders, sometimes mentioning Skia. This is the end of one such log:

A workaround is to run with --disable-gpu, a flag found on this page: https://peter.sh/experiments/chromium-c … -switches/

Re: Most graphics broken on Chromium on AMD laptop; Skia, shader errors

Encountered the same. What worked for me was using --disable-gpu-driver-bug-workarounds. Then it was still GPU accelerated, but without the broken graphics. I have AMD Radeon RX 6750 XT using the open-source driver. But this still does not seem like a permanent solution, there is clearly something wrong somewhere.

Re: Most graphics broken on Chromium on AMD laptop; Skia, shader errors

Owning AMD Ryzen and iGPU, I have the same issue and error log.

Starting chrome with --disable-gpu-driver-bug-workarounds seems like a working workaround but I haven't found out the cause.

Same problem here with AMD Ryzen 7 4700u laptop with iGPU. The workarounds posted here didn't work for me.

Re: Most graphics broken on Chromium on AMD laptop; Skia, shader errors

I don't think it's an issue with the Chromium package. I rolled back to May 2nd mirrorlist (Server=https://archive.archlinux.org/repos/2023/05/02/$repo/os/$arch) and the issue is gone and Chromium is up to date

Same issue here: AMD Ryzen 7 5700G with Radeon Graphics on a Mini PC.
Workaround works for me.

Re: Most graphics broken on Chromium on AMD laptop; Skia, shader errors

hi.

fwiw i have these specs:

OS: Arch Linux x86_64 
Host: MS-7D54 2.0 
Kernel: 6.3.1-zen1-1-zen 
Uptime: 1 hour, 45 mins 
Packages: 811 (pacman) 
Shell: zsh 5.9 
Resolution: 2560x1440 
WM: sway 
Terminal: foot 
CPU: AMD Ryzen 7 5800X3D (16) @ 3.400GHz 
GPU: AMD ATI Radeon RX 6800/6800 XT / 6900 XT 
Memory: 3462MiB / 32017MiB

i was able to get rid of the flickering by removing my ~/.config/chromium directory. i removed my ~/.cache/chromium directory as well, but removing only that one did not fix the problem.

perhaps that helps.

Did you copy any folder to recover extensions and settings after? Or did you start from scratch?

i started from scratch. i don't know the structure of chromium config directories and files. i just finished :Y.

Deleting the folder "GPUCache" in my ~/.config/chromium/Default has resolved my problem without the need of deleting the whole profile,

# rm -rf ~/.config/chromium/Default/GPUCache

this did the trick for me as well while previously I had to switch o Vulkan render in chrome://flags but that broke completely WebGL based sites .... thank you!

Re: Most graphics broken on Chromium on AMD laptop; Skia, shader errors

FYI there was another bug filed and closed as "won't fix - cannot reproduce" https://bugs.chromium.org/p/chromium/is … 442579#c11

users are reporting that removing the GPUCache might be just a temporary fix and that after a while they started seeing again issues here and there (see screenshots attached).

Google Chrome (stable branch) seems to be also affected and I start wondering if this was a mesa update that ruined AMD OS drivers for Chrome (I have zero issues on Firefox) or if it's actually a mainstream Chromium issue that also affects other derived projects (same versioning here for both chrome and chromium)

No need to do that as root.

Re: Most graphics broken on Chromium on AMD laptop; Skia, shader errors

I can confim that deleting the GPUCache folder helped as well, no need for --disable-gpu-driver-bug-workarounds anymore, even after a few reboots.

too much Python code recently, thanks for pointing that out, I always mistake `$` with `#` and use `#` out of programming habit as a comment to actually not even run anything but yeah, no root needed for this!

Deleting the GPUCache folder didn't work for me, but the flag does.

Same, but with google-chrome from the AUR. Deleting ~/.config/google-chrome/Default/GPUCache worked.

Re: Most graphics broken on Chromium on AMD laptop; Skia, shader errors

Just wanted to let you know that I got same issue on linux Ubuntu 22.04.2 LTS, after system update that occurred 2023-07-12. So it's not really arch issue, looks more like chrome/chromium issue related to GPU Cache for user profile.

My card: 07:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 22 [Radeon RX 6700/6700 XT / 6800M] (rev c5) (prog-if 00 [VGA controller])

symptoms: chrome broken, browser window shows bookmarks, but all rendering is broken. Traceback from Chrome, contains these skia shader errors, e.g.:

Fix that worked:

* opening new user-profile from command line with google-chrome --user-data-dir=new_directory (but then you're creating new user profile)
* removing GPUCache directory in .config/google-chrome/Default
