The miPointerSpriteFunc swcursor code expects there to only be a single
framebuffer and when the cursor moves it will undo the damage of the
previous draw, potentially overwriting what ever is there in a new
framebuffer installed after a flip.
This leads to all kind of artifacts, so we need to disable pageflipping
when a swcursor is used.
The code for this has shamelessly been copied from the xf86-video-amdgpu
code.
