Bug 293281

Application: kwin (4.6.5 (4.6.5))
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-12-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

1) Stat smplayer
2) Play a 1080p mkv file
3) After 15 sec aprox, KWin crashes


- Custom settings of the application:

1)Desktop effects activated using OpenGL:
   *Disable-functionality-check option was activated
   *Genral options: +Only running windows
                                  +Smooth
                                  +Suspend-desktop-effects-full-scree-window option was activated
   *OpenGL options: +Frame from image
                                    +Use-VSync option was activated
                                    +Enable-direct-representation
2) Use of nvidia-driver
3) 'gl' was smplayer video-output

- Others:
3) Smplayer gets very slow, so that movie is not played on-demand, it sometimes gets stuck....it seems that resources are very congested at that time....
