<pre>Tvrtko, do you see the same issue also with the offscreen version of the test?
Benchmarks shouldn't normally be doing uploads after test startup, unless its
benchmark for texture upload.
The only thing that I've seen using a lot of blitter during test run-time is X
server, when it does copy of the non-vsynched frame. This would be most
visible when using Intel DDX with DRI2.
What X server and X driver you're using? Intel DDX one, or modesetting? If
former, do you use DRI2 or DRI3?
(LIBGL_DEBUG=verbose should output whether Mesa uses DRI2 or DRI3.)</pre>
