When hardware acceleration is turned on for flash videos 480p videos on Youtube
show the wrong colors; 360p and 720p work fine. Strangely, I've not noticed
problems on any other site but I'm not sure if other sites are using hardware
acceleration since most don't tell you.  I've tested this on Firefox and the
old Opera 12.16 and it happens on both. Disabling hardware acceleration causes
all the videos to have the same colors.

Here are 3 pictures demonstrating the problem.
