Bug ID: 452941
Summary: Crashes when wide window opened
Product: kwin
Version: 5.24.4
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: aar...@doofus.org
Target Milestone: ---
SUMMARY
***
A very wide window split across both of my 4K displays causes kwin_x11 to
repeatedly crash.
STEPS TO REPRODUCE
1. Create an image that is 6144x128 pixels
2. issue the command "gm display -size 6144x128 image.png"
3. Watch kwin repeatedly crash and restart
This also crashes with xv.
OBSERVED RESULT
Whenever I open a very wide window kwin_x11 crashes repeatedly. Note that for
my desktop I have four displays. The top two are both 1920x1200 and are
configured for the upper left. My next two displays are 3840x2160 and are side
by side so my desktop is basically:
1920x1200 1920x1200
3840x2160 3840x2160
The window displaying the image appears along the top split across both of my
4K displays.
EXPECTED RESULT
I expect a very wide window to appear spanning the two 4K displays and for KWin
not to crash
