Original GitHub issue: https://github.com/netblue30/firejail/issues/3012

When playing a video with mpv+vulkan from dolphin, the vulkan renderer is unavailable to mpv with the default dolphin.profile. noroot must be commented out for mpv to access vulkan from within the dolphin container.

To replicate, add gpi-api=vulkan to mpv.conf, and use dolphin to select something to play - mpv will quit immediately as long as dolphin is started with noroot. You may need to explicitly set gpu-context in mpv as well, if your wayland/x11 environment isn't properly detected.

Thanks for reporting the issue. I've put a comment inside the dolphin.profile to add 'ignore noroot' to dolphin.local in such case. I didn't want to drop 'noroot' from the default options, as this doesn't affect most users IMHO. If you can live with that, please test and comment/close this here.

Yes, I think this is fine. However, do you have an idea of what noroot is blocking access to in this case? I have it in my mpv.profile and it does not prevent vulkan renderer usage.
