Default Re: 180.08 & red checkerboard

totem 2.28.2
GStreamer Core Library version 0.10.25

The type of video file seems to have little influence on the pattern but here is one that definitely causes it at least some of the time:

NOTE: this is my personal web server, please do not download this video unless you are nvidia staff or trying to repro the bug as my connection is not that fast!

I have a geforce 8800GT. Bug report attached. The bug is hard to reproduce reliably and seems to happen at random, I just tried several times to provoke it but got nothing. It does happen though and once it starts occuring usually it will continue with some regularity. I agree with the earlier posters, it seems more common when amarok is running. One time I was watching a movie just fine, then unminimized amarok from the systray and bam, red checkered patterns (this is amarok 1.4 by the way, not the newer 2.x series, it uses qt3). The version of amarok 1.4 I am using is the latest from this ppa:

I have attached a bug report. And here is a screenshot of the effect for good measure:

If you need any more info just ask.

I am seeing a similar problem. OpenSuSE 11.2 32-bit with a pair of 9800 GTX+ cards with Twinview, both monitors plugged into the primary card. Driver is 195.36.15. Xine version is libxine1-

During video playback in xine I see a black/red checkerboard covering the entire video window flash for just a moment. This happens whether I'm in window or full screen. It is not readily reproducible. If I see it happen and back up the video, it does not always recur when playback rolls through the same point. Using the above video I was able to see the issue a few times.

It happens whether in mp4 avi or mpg videos with xine. It does not happen in flash videos.

I too would be willing to provide any information to help troubleshoot this issue.
