Hi, I filed a bugreport on GitLab with Mesa concerning this situation: https://gitlab.freedesktop.org/mesa/mesa/-/issues/10523

Have you have ever added any of the following to /etc/profile.d/kwin.sh to help improve kwin performance?

export KWIN_OPENGL_INTERFACE=EGL

export QT_XCB_GL_INTEGRATION=xcb_egl

-Thanks

That was real stupid of me, /var/lib/sddm as was just thinking to clear
sddm cache. I have already done so.

-Apologies

Hi, where is the SDDM cache located on an openSUSE Tumbleweed, KDE
desktop machine?

Hi, so is it best to just post a mesa bug report on this at gitlab?
Kwin
crashes often too after login. Perhaps this is linked to that. Do you
have any ideas in your vast knowledge?

No, sorry, I don't.

I don't see anybody mentioning mesa as the culprit of your problem
with
kwin?

I don't use SDDM or Plasma, but the description reminds me of a similar
issue with a new Mesa version:

HTH, cheers.

Hi, after following the above link suggestions and 6 powercycles with
some desktop usage Kwin does not appear to be crashing any longer. The
problem with SDDM blank fields and window field descriptors does persist
though, (there'-Wishess a flash across the screen when initially keying
first character of the password). Thanks for that weblink insight.
