If I disabled offscreen pixmap, the problem disappears.
The issue here is almost certainly that FbComposite offsets the composite operation by the coordinates of the drawable with no regard to the transformation.
Fixing probably involves making image_from_pict() do the conversion, and somehow fixing up miSourceValidate
Moving to 7.5 tracker. Hacked around in server-1.5-branch, see further discussion on bug #15098 for motivation and workaround doc.
dropping from the release tracker: xaa is deprecated, offscreen pixmaps are not enabled by default, and this _may_ be fixed already.
I believe this is fixed.
