After the a recent software update which included Firefox 12.0 as well as Nvidia drivers and Xorg files. Videos on Youtube are now showing blue people.

It seems that the color palette is out of wack. Reds in videos are showing as Blue and Black is showing as transparent. This strange video behavior bleeds through to other tabs in the browser with black on the current tab that overlays any video black on hidden tab, becomes transparent.
Even some windows that have black text, if put in front of a video opened in Firefox, the black text will become transparent in places.
Had this issue once before about 2 years ago and it disappeared when upgrading to PCLOS 2011. Now it seems to have re emerged.
Anyone know what causes this to occur?
