OS X can't display offset YUV overlays?

Hi. We’ve got a game that needs to be able to display YUV overlays for
playing movies at variable offsets within the SDL window. This works
fine in Windows and Linux, but the OS X version of the game fails to
display YUV overlays in windowed mode if the offset is anything else
than (0, 0). There’s actually a test for this in SDL’s OS X code which
returns failure in these cases, so it seems to be intentional. Why is
this, and is there any chance it could get fixed?
