--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
The bug is actually dependent upon the CRTC being transformed, which should not
be an artefact of OpenGL compositing... That's something to look into as to why
the RandR configuration is different.

Many thanks,

    sna: Remove unitialized use of 'cursor'

    The earlier query of cursor (simply to find out the hw size) was
    replaced by an invariant determined when the cursor was first set.
    However, not all uses of cursor->size were fixed.

    Fixes regression from
