These can't both be true. :) Are you actually in a Wayland session? How are you starting it? How do you know it's a Wayland session?

Ahaha, sorry for tthe confusion. That was just copied from the system info widget while I was back to using the X session. Of course the bug itself occurs in a Wayland session which I know for sure because I chose it in SDDM. ^^

Cool, in that case can you please get a wayland-debug log for Okular by running the following in a terminal?

WAYLAND_DEBUG=1 okular path_to_the_file.pdf > ~/Desktop/okular.log

The UI will still freeze, but hopefully the file will be created anyway, and then you can attach it after you recover from the freeze using your preferred method.

Also, when you say Plasma freezes, is it really only Plasma? Or is it everything, including apps? If global keyboard shortcuts and already-open windows aren's responsive, then it's everything, not just Plasma.

Comment 4 laubblaeser 2023-02-15 16:27:26 UTC

Today's openSUSE Tumbleweed snapshot (20230215) seems to have fixed the issue. I can open PDFs just fine and the system remains usable. Let's consider this a system-specific hiccup and that it has already been fixed. Will report back with some logs if it ever happens again. :)
