Bug ID: 489414
Summary: KWin crashes after disconnecting external display
Classification: Plasma
Product: kwin
Version: 6.1.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: core
Assignee: kwin-bugs-n...@kde.org
Reporter: j...@kaidan.im
CC: davids.paskev...@gmail.com
Target Milestone: ---
SUMMARY
The device is configured to go to sleep once no displays are connected.
The crash happens when the device is woken back up, possibly connected to a new
external display.
The bug is not always reproducible.
This crash didn't happen on my own device, I'm reporting for someone else.
The backtrace is the same as the following sentry report
https://crash-reports.kde.org/organizations/kde/issues/36638/events/ee240964d5b54f0e8371a45b3dae8499/
(It's required to show the Full Stack Trace, as sentry otherwise filters the
relevant parts)
Possibly Output *m_moveResizeOutput in window.h should be stored in a QPointer,
as it seems to be reference counted and not guaranteed to still exist. A check
for whether it is null already exists, but it wouldn't catch a dangling
pointer.
I don't have a development setup for Plasma right now to verify this.
STEPS TO REPRODUCE
1. have laptop go to sleep automatically
2. Disconnect laptop from docking station
3. Wake up laptop connected to other display
