Bug ID: 482452
Summary: Wallpaper all of a sudden becomes incorrectly sized
Classification: Plasma
Product: kwin
Version: 5.27.10
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: sergio.calleg...@gmail.com
Target Milestone: ---
SUMMARY
While one works, all of a sudden the display wallpaper become incorrectly sized
and too small, occupying only the top left corner of the screen, leaving a
black area to the right and to the bottom.
I am experiencing this on an arch derivative (Manjaro) that being a rolling
distro should be completely up to date wrt Plasma components. The setup uses
Wayland.
The problem occurs using 2 screens (laptop screen + external monitor), using
the external monitor as primary, when the external monitor has a very high
resolution (4k). Both screens use scaling for HiDPI (the external monitor,
being very large, employs a more moderate scaling), but I do not know how
relevant this may be.
I have been unable to understand what triggers the problem. When you connect
the monitor, everything is fine. As you work all of a sudden the background
flashes and becomes too small.
Disconnecting and reconnecting the monitor or changing its resolution from the
control panel to then revert it back fixes the issue.
Don't know how important this issue is as of today, since I cannot test on
plasma 6 yet.
STEPS TO REPRODUCE
Unfortunately the issue is erratic and a proper way to reproduce has not been
identified.
OBSERVED RESULT
All of a sudden the wallpaper becomes smaller than the screen estate and top
left aligned, leaving a black area to the right and to the bottom.
EXPECTED RESULT
The wall paper remains OK.
