Do you have an AMD GPU? If so, does your system have the facility to disable it and use an integrated Intel GPU instead — or do you have some other GPU you can use instead? If so, can you temporarily do that, reboot, and see if the issue goes away?

If so, this is a bug in the AMD GPU driver.

Frankly it probably is anyway, but that would help to be sure.

Yes I have an AMD GPU. There is no other GPU in the system.
It also doesn't matter because even with the same config and nothing changed the issues didn't appear again. I just used the bug reporting tool after it did pop-up.
So as long as nobody else reported something similar, I think we can close the issue.

Thanks. Even if you can't reproduce it, it may be a real issue, so we won't close it yet. I'll let the KWin folks take over from here.

Thank you for the bug report, and I'm sorry we weren't able to figure it out yet. A lot has changed since it was reported; can I ask you to see if this is still an issue with Plasma 6.5.3 or later? Thanks a lot!

No worries. I'm on 6.5.4, and I don't remember seeing this issue in the 6.5.3 cycle as well.

Great, thanks!
