Description Dave Flogeras 2021-12-30 16:28:23 UTC 
SUMMARY

Since upgrading to kwin-5.23.4 on Gentoo, logging in results in a white/gray screen.  If I move the mouse around I can tell it changes shape when it passes over windows from my saved session.  If I disable compositing with the keyboard shortcut, I can see the desktop again.  This setup worked well with kwin-5.22.5.

This seems independent of plasma, trying LXQT with kwin results in the same.  This is an old 32bit Dell D820 laptop, with nvidia quadro nvs 110M.  I'm running a 4.19 LTS kernel with nouveau.  The system is otherwise up to date with the exception of the older kernel series.
