When I use OpenGL or VDPAU as the video output device in MPlayer, the screen goes blank for a second and resumes what it is doing to playback a video file. This happens any time and with any video file, so it is repeatable. When I am using XVideo as the video output device in MPlayer, the screen does not flicker for a second and resumes what it is doing. This does not just happen in MPlayer, it happens when an application requires OpenGL or VDPAU for graphics. This did not happen in previous versions of nVidia's proprietary module which was several versions ago. Now I am getting annoyed that this is not fix after a few module upgrades later. Also I tried a few distributions and they have the same problems.
The setup is as follows:
Dell Inspiron 1520
Intel Core 2 Duo T7300
2 GiB DDR2-667
GeForce8 8400M GS
The following is after running "/usr/bin/nvidia-bug-report.sh":
I did not yet use "startx -- -logverbose 6".
