Fedora :: White Screen With IPlayer In Fullscreen

I'm running Fedora 13 (64-bit) on a Dell Inspiron 1525 laptop with integrated Intel graphics (lspci reports it as: 00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)), and am having a strange problem with watching iPlayer in fullscreen.The video will work fine in the web browser at default size, and most times even in fullscreen as well, but sometimes on switching it to fullscreen the entire screen goes white with only the cursor visible. The sound keeps on playing and the cursor responds to mouse movements but I haven't been able to do anything to fix the screen (I tried bringing up a terminal and logging out, as well as doing a "compiz --replace" but neither had any visible effect - obviously I may have typed them wrong since the screen was white, but I tried multiple times). As mentioned above, I am using Compiz desktop effects, and also had to check the "Unredirect Fullscreen Windows" box in CCSM to get iPlayer to play video in fullscreen in the first place.

The annoying thing is that I haven't been able to consistently reproduce the error, in that sometimes it takes multiple attempts of going fullscreen and/or videos for it to occur. However, it has been pretty consistent in that it has only taken a couple of different videos to be played for it to happen (oddly I don't think I've had it happen on the first fullscreen attempt of the first video yet, but that might not mean anything).
