Description Andrew Athalye 2022-01-24 03:16:43 UTC
On an NVIDIA RTX 2070S running Sway with Nvidia-GBM, Google Chrome fails to initialise hardware-acceleration unless the seccomp bpf sandbox is disabled. Using a trunk build of Chromium, the failure message contains the characteristic keywords: "MESA-LOADER: failed to open ...: Unable to open shared object file: Permission denied." This seemed similar to selinux / flatpak sandbox-violation errors I had seen before on other systems, so I tried disabling the bpf sandbox, which caused the errors to disappear and acceleration to work as it does under X11 (correctly). On Google Chrome, the MESA error is not displayed, but the results are identical and the same resolution can be applied.

I am unsure if this bug should be submitted directly to the Chromium bug tracker, since I have no experience running NVIDIA + Wayland on distros other than Gentoo.

Reproducible: Always

Steps to Reproduce:
1. Run Google Chrome with the arguments "--ozone-platform=wayland"
2. Check the console and chrome://gpu
3. Observe the message "Hardware accelerated but at reduced performance" next to WebGL(2), and the Problem Detected "Gpu compositing has been disabled..."
Actual Results:  
The browser has reverted to software rendering and the above error message is displayed in chrome://gpu. There are also several errors in the console related to MESA-LOADER and CreateCommandBuffer if using Chromium instead of Google Chrome.

Expected Results:  
GPU Acceleration should work, provided that the NVIDIA Driver is installed with a version suitable for GBM / Mesa support.

On systems with XWayland, this can be avoided by using the X11 version of Chrome, however the Wayland version is functional with the workaround (disabling sandbox).

Comment 1 Stephan Hartmann gentoo-dev 2022-01-24 11:53:10 UTC
Maybe https://crbug.com/1256824 ? The reporter claims that it works with current google-chrome-beta (M98).
Comment 2 Andrew Athalye 2022-01-24 22:44:37 UTC
I was able to reproduce it with Chromium from the appspot download site (basically the trunk build), however I'll check Google Chrome Beta to see if maybe they have some build flags enabled that make it work there.

After a very brief check using www-client/google-chrome-beta, I was able to reproduce the same behaviour where Hardware compositing is only functional if the bpf sandbox is disabled. When I have some free time I'll look into the chromium source to see if a modification to the sandbox to exempt the syscall for loading the NVIDIA shared object files would work.
Comment 4 Andrew Athalye 2022-01-24 22:49:28 UTC
Just one final comment: in the Beta build I tried, Canvas was listed as hardware accelerated under Wayland in chrome://gpu, but Compositing was still software-only. This may be the change that the crbug was alluding to, as in the Chromium trunk build this was also the case. No hardware acceleration at all works by default in the stable build.
Comment 5 onkobu 2022-02-09 07:54:29 UTC
Have the same on an AMDGPU with google-chrome-98.0.4758.80 on X11. Works with google-chrome-beta-99.0.4844.17. 

Interestingly starts on a machine with nvidia-drivers-510.47.03. But freezes X11 then which has always been the case on that particular machine/ setup also with previous versions.

Forget about my comment #5, context totally wrong.
