Sounds like a regression in the radeon driver. Does the issue also happen on an older kernel?
(In reply to Zamundaaa from comment #1) > Sounds like a regression in the radeon driver. Does the issue also happen on > an older kernel? My system is opensuse tumbleweed-slowroll, recently changed from from tumbleweed. These rolling distros. don't give a lot in the way of options but I did take note of versions in grub I am currently booting to the kernel 6.9.9-1 and I just tried it on the only other option which is 6.8.7-1. Same result. That said, I think it's something else because this weekend I had to reinstall my OS from scratch as it had some btrfs error that it couldn't repair. I noticed a couple of things. With a completely fresh install I was able to boot into wayland again so that's with it's latest kernel. However, I did a few things, I: - added pacman for video - booted into KDE X11 - added a few apps I needed. After this I could no longer log into KDE/Wayland, and out of curiosity I tried a few things: - I removed pacman and did a vendor swap back to opensuse, still couldn't not log in. - I created a new user and tried to log in there, no change. I find it hard to believe that little utilities I added caused this, things like htop. I did add some major apps: zoom, signal, slack but I don't see how these could affect it, yet alone a clean install. I kind of wonder if logging into KDE/X11 threw some sort of a switch that made logging into KDE/wayland fail. Anyway, I am a developer, not in this area so you will still have to help me along but it means I know enough where I could give you more information if you think it will help, system logs or whatever you want.

Sorry, this kind of got lost in my emails. It sounds a lot like a problem with the distribution. Could you test if you experience the same issue on a different one?
It's been a long time since this issue was last commented on. A lot has been improved and fixed since then. I had seen this symptom on my own machine a few times, but it's not been a problem in months. Are you still experiencing this bug on KDE Plasma 6.5.1 or later? Thanks.
