<pre>Buffer swapping was broken in commit cac7c8dc4b154d37ff27430aa7b714ac84f3d092.
When rendering 3D graphics, old buffer contents show up between all rendered
frames. This happens in both fullscreen and windowed mode.
The problem is visible on Haswell and Broadwell but not on Skylake, with both
DRI2 and DRI3. It can be easily seen when running a GPU intensive program like
FurMark.</pre>
