i think I have identified a problem with 6.12.2 on a RS690 Chipset:
When doing XvPutImage (via textured video) with a src offset !=0
(src_x or src_y), the driver does the wrong thing compared to all other
cards and drivers I have seen:
The picture is then shifted to down and right, with invalid framebuffer
data filling the left and upper part of the screen.
For my card, I can fix this behaviour with the following patch. This
isn't a proper patch yet, but should illustrate what needs to be
changed: The offset need not be applied to the dst address, just the
Don't know if this breaks other cards - it probably does.
