Bug ID: 378878
Summary: KWin crashes with some QT errors
Product: kwin
Version: 5.9.4
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: mrader3...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.9.4)
(Compiled from sources)
Qt Version: 5.8.0
Frameworks Version: 5.33.0
Operating System: Linux 4.10.10-1-ck x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- Unusual behavior I noticed:
Just after login via LightDM I've got this crash, resulting in KWin falling
back to no-effects mode. Also, Latte-Dock was not able to autostart (though I
think it's because of not having OpenGL compositing and stuff). If I go to
systemsettings and re-enable OpenGL, everything works fine.
I think that may be related to Plasma 5 crashes with QT 5.8.0, as I've seen
patches in Arch's repos with their name suggesting that something's wrong with
"latest Plasma + QT 5.8" combo.
I have my KDE apps compiled via makepkg with -O2 and -{march,mtune}=native
optimisation flags it matters.
This issue happens randomly, although I've encountered it a few times in the
last four days.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
