Description Sylvain BERTRAND 2015-06-28 18:10:37 UTC 
play "the reunion"/"propulsion flings"
Without R600_DEBUG=switch_on_eop, glitches are unbearable.
With R600_DEBUG=switch_on_eop, nearly 0 glitch.

latest linux from agd5f linux 4.1 fixes. drm/llvm/mesa/xserver/xf86-video-ati
straight from git (yesterday)

Comment 2 Sylvain BERTRAND 2015-06-28 18:17:46 UTC 
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 Gustaw Smolarczyk 2015-07-16 21:24:02 UTC 
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 Sylvain BERTRAND 2015-07-29 01:28:35 UTC 
In dota2 source 1, if, additionally, I do enable vsync, it seems that 100% of the glitches are gone.
Comment 5 Sylvain BERTRAND 2015-07-29 21:50:41 UTC 
I was wrong, vsync makes the remaining glitches more rare, but still around.
Comment 6 Marek Olšák 2015-08-02 22:31:21 UTC 
Would please test Mesa master? I think commit b0528118dfb1af00e7d08cdb637191b80 should fix this.
Comment 7 Sylvain BERTRAND 2015-08-03 23:52:49 UTC 
Checked portal2 and dota2, they both seem fine.
fixed.
