Some small but important taken-for-granted things functioning like screen and audio sharing/recording in wayland. Yes, I know sometimes with some apps/distros it works. But it needs to work all the time on all reasonably current hardware everywhere. Wayland is getting there, but we’re still a ways off and X11 has its own issues. It feels like we’re 80% of the way there for feature parity and stability vs Windows and MacOS, but this last 20% stretch is feeling like an eternity. The bugginess and lack of features stretches to multi-monitor support as well. Plus we’ve got a bunch of distros threatening off and on to remove 32bit libraries, which would really hamper software support that’s already anemic to begin with… There’s no one single blockbuster issue. It’s just little everyday things that produce just enough friction to keep the unwashed masses away.
I’ve had similarly described visual issues in the recent past on an amd rx 7600xt under Bazzite (based on Fedora 42). It turned out to be the cable was failing. Swapped cables and it hasn’t happened since.
