[SOLVED] KDE Plasma applications crash on Wayland

Anyone using KDE Plasma on Wayland?

Many Kwin applications crash (but they obviously work on X11), as well Zoom, Skype and Teams for what I've seen.

Are there additional packages other than plasma-wayland-session and (since I use nvidia) egl-wayland required to make these applications work properly?
Or is it just Wayland still requiring more time?

Re: [SOLVED] KDE Plasma applications crash on Wayland

Here is another backtrace.

Still plasmashell crashing but saying "signal: Aborted" instead of "signal: Segmentation fault".
Also, this time the crash didn't occur right after login but simply while I was navigating through the applications' menu.

Application: Plasma (plasmashell), signal: Aborted

Re: [SOLVED] KDE Plasma applications crash on Wayland

The traces show that the crash is in the nouveau driver, not Plasma's fault.

Re: [SOLVED] KDE Plasma applications crash on Wayland

I see... could there be something wrong with the package then?

Or is it just a compatibility issue between nouveau and wayland?

Re: [SOLVED] KDE Plasma applications crash on Wayland

Hi, I'm sorry to insist. I don't mean to be annoying.
I'm just curious if there is anyone who can help me with this issue.

It's not a matter of life or death, since I have a working X11 session.
Still, I'd like to find out if there's anything I can do to make Nouveau work better on Wayland.

Thank you in advance

Re: [SOLVED] KDE Plasma applications crash on Wayland

The crash is in nouveau_dri which is part of mesa. If you want to help fix this,  compile mesa with debug traces and report the issue upstream: https://gitlab.freedesktop.org/mesa/mesa/-/issues/

However see some of the existing bug reports like https://gitlab.freedesktop.org/mesa/mesa/-/issues/1166 and the linked https://bugreports.qt.io/browse/QTBUG-76116 that even has some steps to try.
