Bug ID: 398992
Summary: KWin occasionally crashes while going (into/out of)
fullscreen with mpv
Product: kwin
Version: 5.13.5
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: k...@dragonic.eu
Target Milestone: ---
Application: kwin_x11 (5.13.5)
Qt Version: 5.11.2
Frameworks Version: 5.50.0
Operating System: Linux 4.18.9-1-ck-skylake x86_64
Distribution: "Arch Linux"
-- Information about the crash:
What I was doing when the application crashed: Leaving fullscreen in mpv media
player.
Unusual behavior I noticed: Extra screen flicker, weird black boxes in the
lower right corner of the screen while fullscreen in mpv (doesn't happen under
Xfwm4, see: https://i.imgur.com/fiiwcpO.png - quite odd, normal KDE applets are
under those boxes, but not also under...)
Settings:
- KWin: Compositor enabled w/ OpenGL 3.1, scale method accurate, vsync
automatic, applications allowed to block compositioning, instant animations
(slider completely to the left). Effects enabled: Track mouse, Zoom, Desaturate
Unresponsive, Screen Edge, Translucency, WIndow Aperture, Desktop Grid, Present
Windows. Focus stealing prevention none.
- mpv.conf: vo=vaapi hwdec=vaapi hwdec-codecs=all video-sync=display-resample
interpolation tscale=oversample
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".
