Summary: KWin color management segfault when disconnecting a
screen
Classification: Plasma

Status: REPORTED
Keywords: drkonqi
Severity: crash

Target Milestone: ---
Application: kwin_wayland (6.4.3)
ApplicationNotResponding [ANR]: false
Qt Version: 6.9.1
Frameworks Version: 6.16.0
Operating System: Linux 6.14.0-27-generic x86_64
Windowing System: Wayland
Distribution: KDE neon User Edition
DrKonqi: 6.4.3 [CoredumpBackend]
-- Information about the crash:
Since upgrading to KDE Neon 6.4.3, most of the time I disconnect a screen, KWin
crashes. It's been this same error every time - this segfault in the color
management code.
I've been able to frequently reproduce this on an Intel Framework laptop as
well as a ThinkPad with an Nvidia GPU, both running the same version of KDE
Neon. So far I've only tested going through a ThinkPad Thunderbolt dock,
connecting 1440p DisplayPort monitors, but after I finish typing up this report
I'll try some HDMI configrations with and without the dock as well.
The crash can be reproduced sometimes.
