When enabling dri3 in our Xorg driver we caught a number of viewport bugs in
mesa core dri3 using glretrace with various game traces. We currently do not
support page-flipping in our xorg driver, which might be why this wasn't
caught, but that would otherwise be a good candidate for automated testing:

Generate apitraces with frequent window resizing, and automate glretraces with
image capture and image comparisons, and in addition find a way to trigger
transition to- and from page-flipping.
