It's the same with dota2 source 1.
Dota2 reborn is so glitchy, it's unplayable with or without
R600_DEBUG=switch_on_eop.

I can confirm that with Portal 2. It happens on my Tahiti Pro too. And
R600_DEBUG=switch_on_eop fixes this issue.

In dota2 source 1, if, additionally, I do enable vsync, it seems that 100% of
the glitches are gone.

I was wrong, vsync makes the remaining glitches more rare, but still around.

Would please test Mesa master? I think commit b0528118dfb1af00e7d08cdb637191b80
should fix this.
