[Mageia-dev] KWin Segfault - sporatic

[Robert Fox]

I have been experiencing a sporadic KWin segfault crash - it can not be
forced and happens very rarely.  When it does happen, I can not access
the KDE panel anymore, but the desktop continues to work.  The only
resolve it to logout and restart KDE -

Here is the backtrace:

KDE Application: KWin (kwin), signal: Segmentation fault
