Wayland’s “betterness” all requires technical arguments and none of Wayland’s “betterness” is apparent on the screen. Even worse Wayland’s “betterness” is only better if breaking user systems is ok.
It’s developer’s are assholes for creating all the problems you have.
the mouse pointer straight up stutters/stops when the system is under some kind of load… like, say, starting firefox. Not sure if it's CPU load or GPU load but it's a pretty low threshold somewhere. Maybe firefox starting is blocking some screen drawing thing?
Anyway I'm logging out and back into X11 before I punch my screen on impulse.
I personally find colour management to work better than x11 lately, but that might not be for everyone.
