I've had some problems with Dota2 ingame rendering for a while now. The icons on the minimap flickers and some parts of the ground too. The ground only flickers if normal maps are turned on. I have uploaded two videos on github to demonstrate the issue: https://github.com/DarkDefender/dota2_reborn_issue Here is the issue on the Dota2 reborn bugtracker: https://github.com/ValveSoftware/Dota-2-Reborn/issues/150 It seems like this commit broke the ingame rendering: http://cgit.freedesktop.org/mesa/mesa/commit/?id=af4b9c7c2e119d373f9684119b833a8b62cbb756 With the previous commit: http://cgit.freedesktop.org/mesa/mesa/commit/?id=e4339bc9886a26d75b924ad045c3ddd003f802c3 it seems to render fine.
Reverting those commits fixed the flickering on my tahiti xt.

As far as I can see, yes, removing only the TGSI_SEMANTIC_CLIPDIST case mak= es the corrupted texture flicker and the shadow flicker go away.
Seems to solve it for me also. I'm guessing that this is just a temporary workaround?
(In reply to Sebastian Parborg from comment #4) > I'm guessing that this is just a temporary worka= round? No, I think it's the proper fix. TGSI_SEMANTIC_CLIPDIST values are also pas= sed to the pixel shader as a varying, so they need to be counted here. I'll submit the patch to the mesa-dev mailing list for review.
