--- Comment #2 from Sylvain BERTRAND sylvain.bertrand@gmail.com --- It's the same with dota2 source 1. Dota2 reborn is so glitchy, it's unplayable with or without R600_DEBUG=switch_on_eop.

--- Comment #3 from Gustaw Smolarczyk wielkiegie@gmail.com --- I can confirm that with Portal 2. It happens on my Tahiti Pro too. And R600_DEBUG=switch_on_eop fixes this issue.

--- Comment #4 from Sylvain BERTRAND sylvain.bertrand@gmail.com --- In dota2 source 1, if, additionally, I do enable vsync, it seems that 100% of the glitches are gone.

--- Comment #5 from Sylvain BERTRAND sylvain.bertrand@gmail.com --- I was wrong, vsync makes the remaining glitches more rare, but still around.

--- Comment #6 from Marek Olšák maraeo@gmail.com --- Would please test Mesa master? I think commit b0528118dfb1af00e7d08cdb637191b80 should fix this.
