Bug ID: 522405
Summary: Green screen with small black box around cursor
visible for a fraction of a second immediately after
login/logout, possibly related to kernel warning
Classification: Plasma
Product: kwin
Version First 6.7.0
Reported In:

OS: Linux
Status: REPORTED

DESCRIPTION
Quite often after login and logout, I see a green screen with a small black box
around the cursor for a fraction of a second. Today I noticed that I sometimes
get a kernel warning which occurs around the same time. This warning started to
appear with kernel 7.0-rc1 and still appears with the recent 7.2-rc1 release.
I am using SDDM as login/display manager with auto-login enabled and I am
running the default Plasma Wayland session.
This issue (the green screen) started with the latest Plasma 6.7.0 release, the
kernel warning might be unrelated, but it is caused by a change concerning the
cursor plane (which I guess is related to this issue).
To reproduce the issue, I just have to login/logout several times in a row.
