Jonathan,
One question still.
I found the root cause of the firefox issue. But there is one thing
need your advice. You know if the screen resolution is 1280x1024, and the first
pass result of PictOpOver need maximum 1280x1024x4(ARGB8888) size. But if our
driver's framebuffer is not big enough, how do we do that?
Thanks,
Frank

Since the source is typically a 1-pixel "solid colour" image in this
situation, the stride of that image would not be directly relevant. The
stride of the destination would be independent of both source and mask.
Looking very briefly at your code, it seems that you are using a
temporary image to expand the source colour to cover the required area.
You are, of course, in complete control of that temporary image, so you
can use any stride you like that does not cause overlaps.
