nothing happens...

fixed by

kmille@linbox:firejail cat pavucontrol.local 
ignore no3d

Can you tell me why/how tihs broke? git log says the no3d is not new in the pavucontrol profile. But the issue only happens since last system update (Arch - using -git version of firejail)

Some mesa (or gtk/gdk or ...) update broke software rendering I guess.
