Bug Description
I encounter a reproducable hard system lock when I run glxgears and then start a movie in gmplayer.
This only appears when using KDE4 and enable desktop effects (it doesn't matter which of them are enabled).
The steps to reproduce:
1. Log into KDE4
2. open a konsole and run glxgears
3. open a movie in gmplayer (mplayer/
4. wait a few seconds for the crash
The result is:
1. primary display goes off
2. secondary display freezes
3. keyboard unresponsive
4. even SSH doesn't work any longer
This issue cannot be raised within XFCE or within KDE4 without using effects with the same applications so it must be something within plasma/kwin.
No messages are given nowhere when it crashes. It just locks at some point.
System hardware:
- AMD Athlon 64 X2 4400+
- ATI Radeon X1950 XTX
Software environment:
- Kubuntu 9.04 Jaunty Jackalope
- KDE 4.2.2 (proposed)
- xserver-
In addition to the result above I also successfully raised a similar issue by just running gmplayer and while playing a movie moving the controller window around the screen. After some seconds either both displays go off and I have a hardlock again or the screen just freezes and nothing happens (mouse pointer still moving = HW-cursor, keyboard dead). But in the second case I can still log in via SSH and I see in "top" that the system just does nothing.

The top after the second crash case where you can see that X/kwin/plasma just freezed. Still no error messages anywhere.
