Description

Currently WebRender hardware acceleration is broken in Firefox if running in a Wayland session with the proprietary Nvidia driver. Instead, Firefox falls back to software rendering. This is because access to the necessary loader files from egl-wayland (https://github.com/NVIDIA/egl-wayland) is denied by the current profile. The loader files reside in /usr/share/egl/ which is currently not whitelisted in etc/inc/whitelist-usr-share-common.inc

Programs other than Firefox depending on egl-wayland might also be affected.

Steps to Reproduce

  1. Run Firefox Nightly with firejail on Wayland with the nvidia driver
  2. Open about:support
  3. Scroll down to the Graphics section

Expected behavior

Compositing should read: Webrender, GPU 1 show the Nvidia GPU -> indicating hardware acceleration

Actual behavior

Compositing reads: Webrender (Software), GPU 1 shows llvmpipe -> indicating software rendering

Behavior without a profile

With --noprofile Firefox behaves as expected

Environment

  • Arch Linux with nvidia 510.47
  • Firejail version 0.9.68rc1

Checklist

  • The issues is caused by firejail (i.e. running the program by path (e.g. /usr/bin/vlc) "fixes" it).
  • I can reproduce the issue without custom modifications (e.g. globals.local).
  • The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
  • The profile (and redirect profile if exists) hasn't already been fixed upstream.
  • I have performed a short search for similar issues (to avoid opening a duplicate).
    • I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.

Log

Output of strace -f firefox | grep /usr/share/egl/ (without firejail)
