ok, this seems to be rather a snap bug as none of my installed snaps get GPU access right now

Do you have multiple GPUs ? Can you share `about:support` ?

Can you elaborate what are those Snaps? Firefox versions or other software ?

no, only a single GPU. Its a desktop machine. I have downgraded the driver so I dont think about:support would create anything but noise.

Anything really. e.g. https://snapcraft.io/ogre crashed with some EGL init error.
