Comment 1 David Edmundson 2019-09-27 20:42:52 UTC
Can I have the output of xrandr -q before and after

Does this happen on lock or suspend?

After restoring the screens position, I also get bug
"show only application on current screen" shows no applications https://bugs.kde.org/show_bug.cgi?id=404295
triggered
Comment 3 Germano Massullo 2019-10-03 13:28:28 UTC
I noticed that this happens also when the screens go into sleep mode and then you wake up them

journalctl

Today I wanted to collect some journalctl logs. So I locked the session, and waited until I have noticed that the Plasma screenlock view was overlapping in the two monitors. Then I unlocked the session and collected the journalctl messages that appeared just after the problem has been triggered.
Comment 5 Germano Massullo 2019-10-16 15:08:51 UTC
Is there anything else I can do to help debugging this bug?
Comment 6 Roman Gilg 2019-11-01 01:47:38 UTC
Let's continue discussion in 413627. There is some more information already about a potential fix.
