Ah I forgot to mention all the bug reports on the net which are maybe correlated to this bug.
There seems to be an issue with libdrm-2.4.101 but Guix is still on libdrm-2.4.100: https://gitlab.freedesktop.org/mesa/drm/-/issues/39 The Mozilla upstream bug is https://bugzilla.mozilla.org/show_bug.cgi?id=1623885 I also found a bug about hardware acceleration requires LLVM to be whitelisted, but I couldn't find any "Permission denied" errors in the logs. While running Icecat with `MOZ_SANDBOX_LOGGING=1` set. https://github.com/netblue30/firejail/issues/2106
