<pre>Ok, it makes sense. The important detail is that the Window is redirected and
dramatically changed shape and was clipped in between the GL client grabbing
its backbuffer and performing the swapbuffer.

sna/dri2: Early return for empty DRI2CopyRegion
It's possible if the Window is redirected whilst the client render for
its backbuffer to no longer overlap with the visible Window. In this
case, we attempt to copy an empty region, but it debugging is enabled
this throws an assert.
