I have a laptop with a nvidia card and nothing works. From the installers crashing, windows freezing, full desktop freezes, awful performance, awful battery life under Wayland, every glitch under the sun from minor lines appearing on the screen to potentially physically damaging glitches like rapid flickering, and every other issue you could possibly imagine: it happened.
I mean it happened in like the week total combined that I was testing GNOME/KDE. Probably if I spent any more time on it my computer would explode?
Meanwhile X11 with i3 just fucking rocks. Smooth and stable like nothing else.
