What GPU do you have? Also how do you get to the screen shown in the artifact screenshot? An RX 480. The screen appears after queuing for a game in dota. Once the matchmaking system finds a suitable game for you, such pop-up will appear in the game for you so you can decide to either join or cancel. Here are repro instructions on how to get to that screen in Dota without having to join a public match: 1. Go to Arcade -> Overthrow 2. Create Custom Lobby 3. Set lobby password 4. Create 5. Click Start Game Bisected it to commit ad11fc3571e025b22d9feed80a7f499665f7a255 (refs/bisect/bad) Author: Dave Airlie <airlied@redhat.com> Date: Thu Jan 11 08:02:52 2018 +1000 radv: don't emit unneeded vertex state. If the number of instances hasn't changed and we've already emitted it, don't emit it again. If the vertex shader is the same and the first_instance, vertex_offset haven't changed don't emit them again. This increases the fps in GL_vs_VK -t 1 -m -api vk from around 40 to around 60 here, it may not impact anything else. Dieter also reported smoketest going from 1060->1200 fps.

I my self probably don't have the know-how to compile & replace your patched mesa with my system's mesa to verify the fix. Since you use Arch, it may be worth building/running https://aur.archlinux.org/packages/mesa-git/ Can confirm that since mesa 18.0.1-1 the issue has been fixed for me. Thank you for the work! |
