Bug ID: 456678
Summary: KWin isn’t painting/drawing window updates to an
external monitor
Product: kwin
Version: 5.24.6
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: xrandr
Assignee: kwin-bugs-n...@kde.org
Reporter: arusa...@gmail.com
Target Milestone: ---
SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
When attempting to use an external monitor with my laptop, the monitor display
doesn't update or repaint when there are windows on the display. Additionally,
it doesn't display a wallpaper. I am using X11.
STEPS TO REPRODUCE
1. I connect an external monitor
2. I opt to extend my display to it
OBSERVED RESULT
- It does not display my wallpaper (is an all-black screen)
- I *can* move my mouse cursor to it
- If I drag a window to it, the window does not display
- My mouse cursor updates to indicate I can resize or select text when hovering
over where the window should be
- If I change the position of the display from KScreen, the display updates,
showing my wallpaper and the window
- The window doesn't appear to be interactive
- I can drag the window back to my primary display, where it is interactive
once more
This happens even if I opt to make the display my primary one and disable the
other.
EXPECTED RESULT
The screen should be extended, the wallpaper should show, and windows on that
display should be fully interactive and update accordingly.
