Default Re: Weird color damage with 9631 after upgrade to 6.2-RELEASE

Update: I did some more research on the nature of that color distortion. It seems like card interpretes each RGB8 value (24 bits, 8 for each color component) as RBG4 (12 bits, 4 bits for each component, red-blue-green order).
Thus, color which is 0xFF0000 (red) looks like magenta onscreen (red = 0xF, green = 0x0, blue = 0xF).

Nothing suspicious in the log though:

Also I've forgot to mention that nv driver works without any problems. But there's no OpenGL acceleration for nv
