Bug ID: 528488
Summary: Freeze or Crash when using zones with shift or by
dragging to the edge
Classification: Plasma
Product: kwin
Version First 6.8.2
Reported In:
Platform: CachyOS
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-crash
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
DESCRIPTION
When I try to assign a window to the zone, by dragging it and holding shift, or
when dragging window to the edge to make it half/full screen, the whole desktop
freezes. The freeze happens right as when the zones are about to be printed on
the screen. The freeze can be so hard that it causes everything to crash and I
have to restart window applications. The freeze does not log me out. The bug
can't be 100% consistently triggered, because if it already froze and the zones
are "loaded/cached", it's difficult to reproduce. After some time passes it may
become possible to reproduce again.
I've tested it on nvidia drivers: 610.57.04 and 615.78.08, and kernel
7.3.1-1-cachyos and 6.18.55-2 LTS
I have two displays:
1. 3440x1440, 160Hz, HDR
2. 1920x1200, 60Hz
Disabling HDR on the first display "fixes" or prevents the issue from
happening. I'm 90% confident that setting it to 60Hz may also fix it, but
because of the "cached" zones I'm not 100% sure.
STEPS TO REPRODUCE
1. Log in
2. Open window
3A. Drag it and start holding shift
3B. Drag it to the edge of monitor
4. Freeze
OBSERVED RESULT
Whole desktop freezes. The cursor is not moving, and the zones are not
displayed. When it unfreezes the window may be snapped properly. Sometimes the
freeze is so hard that whole compositor(?) crashes and the windows are gone.
EXPECTED RESULT
The zones are being drawn properly and the window gets snapped.
