Hi there,
Every once in a while (a couple of times a day) my window manager crashes, taking away every window’s titlebar and i get a kde message telling me the window manager had crashed. I get following backtrace:
Application: KDE Window Decorator (kde4-window-decorator), signal SIGSEGV

To get my titlebars back, I just open the “Desktp Effects” CompizSettings and hit the Checkmark. That’s bringing everything back.
Can anyone tell me why this keeps happening? It’s kind of annoying…
and is anyone experiencing the same problem?
Btw. I’m using OSS11 with KDE 4.1.1.
Thanks,
Ron
