Well, look no further, this is your issue. I tried using the modesetting driver
and got absolute garbage out. Stale rendering, extreme slowness. Why didn't I
think of this before...

Anyway, will try to see if I can fix this issue. Seems like I will have a happy
time in glamor and mesa's code tomorrow.

Thanks, because you are the first one who finally answered me and provided me
with real information.
