Now, I think the nvidia-555/wayland problems might finally be fixed on firefox-nightly knocks on wood. I've been watching youtube on it for about an hour and it hasn't crashed yet, and about:support says I'm running in wayland mode, not X11.
I copied my minecraft files from Windows, everything works the same, except my shader pack just renders nothing. Turning off the shaders works fine. I think these shaders used to work on old Fedora, too. Any ideas?
