Bug ID: 452281
Summary: Application Windows moving randomly from screen to
screen and sometimes to other desktops
Product: kwin
Version: 5.24.4
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: jpha...@gmail.com
Target Milestone: ---
SUMMARY
Since a major KDE upgrade a few weeks ago, application windows on my 3 monitor,
4 desktop Plasma machine have been moving at random times to another screen on
the same desktop, or less often, to another desktop on the cube.
At first I thought it was to do with screen saver cutting in, but it happens
randomly before that happens.
I have 3 4k screens with the leftmost being primary. After a short (<1 hour)
period all app windows in screen 3 suddenly move, usually to the middle screen
of the 3, but not always. Sometimes the windows move to the primary, leftmost
screen, and sometimes they have moved to desktop 4. I have not seen a move
desktops 2 or 3.
OpenSuSE Tumbleweed 20220403 (but has been around for a few upgrades).
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.92.0
Qt Version: 5.15.2
Kernel Version: 5.16.15-1-default (64-bit)
Graphics Platform: X11
Processors: 24 × AMD Ryzen 9 3900X 12-Core Processor
Memory: 46.9 GiB of RAM
Graphics Processor: AMD DIMGREY_CAVEFISH
ADDITIONAL INFORMATION
The problem makes one of the 3 screens quite unusable.
Problem has persisted across a few SuSE (and at least one kernel) and Plasma
updates. Please let me know if I can help with deeper debugging info -
installing debug symbols, etc.
I did discuss this on the KDE Community Forums, and got an answer that the new
release had a lot of new code, but it's been a while.
