Bug ID: 416998
Summary: kwin_x11 crash during youtube videos
Product: kwin
Version: 5.17.5
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: s...@kabelfunk.de
Target Milestone: ---
kwin_x11 freezes from time to time, especially when watching youtube videos
(about 1x per week). The sound continues to play, keyboard and mouse also work,
but the screen content is frozen.
To restore the desktop, I pressed Ctrl-Alt-Backspace and logged in via
password. The crash information comes after that time (from the KDe tool
DrKonqi?!).
I tried to install has much debug symbols as possible.
The issue has never occurred when the compositor is disabled (Shift-Alt-F12).
Application: kwin_x11 (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
