Alex,

	I have already found and fixed this bug. Just as previous mail mentions, when in the following condition(PictOpOver):
	1)pSrc : PICT_a8r8g8b8 pMsk:0 pDst: PICT_r5g6b5
	The coordinate of X is out of the source picture that leads to the wrong rendering in the region we don't want.

Thanks,
Frank

Make sure you are properly flushing the caches in your drawing engine?
