Bug ID: 419085
Summary: kwin_x11 misbehavior and crash with existing
workspaces
Product: kwin
Version: 5.18.3
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: ryu.ketsu...@outlook.com
Target Milestone: ---
Application: kwin_x11 (5.18.3)
Qt Version: 5.14.1
Frameworks Version: 5.67.0
Operating System: Linux 5.5.9-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"
-- Information about the crash:
- What I was doing when the application crashed:
This happened after I update Plasma but continues after downgrading to Plasma
5.18.3 (Going from Unstable Repos to Stable Repos). The Virtual Workspaces
turned useless except for the one at the middle (I have three). Every time I
try to use the one at the left or at the right, nothing shows up, being only a
black screen. If I try removing and adding virtual workspaces, KWin crashes
completely and reloads with no compositor enabled.
- Unusual behavior I noticed:
If I open KRunner through the keyboard shortcut while I'm still at one of the
other workspaces, I'm thrown back at the one in the middle.
KWin disables compositing everytime a crash happens.
Only X11 session is affected. Plasma Wayland and kwin_wayland does not show the
same issues.
- Extra note:
I require X11 for Global Menu to work and it is part of my workflow to have it
as well the three virtual desktops. If it's possible for this to be addressed
as soon as possible or to present me a way to fix it which does not involve
sacrificing my whole user folder...
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
