Created attachment 137850 [details] Wine log with Mesa git The Witcher run under Wine fails to launch. Essentially, it hangs indefinitely before any video output but the game can be closed with Ctrl-C, and no ill effects are seen otherwise. Reverting commit b650fc09c3a35ca624aad5fe4b5c34867708f116 in Mesa works around the issue. The game also works fine with a Nvidia 980ti and 390.25 binary drivers.

Created attachment 137851 [details] Wine log with mesa git and reverted commit
I'm no mesa dev but could you test with and before bc65dcab3bc48673ff6180afb036561a4b8b1119 ? This might be a dupe of https://bugs.freedesktop.org/show_bug.cgi?id=105339 Unless you're sure your error started happening since b650fc09c3a35ca624aad5fe4b5c34867708f116

The game launches fine for me with mesa from git are you still having issues?
Yeah I suspect the following commit fixed it: commit 7083ac7290a0c37a45494437a45441112f3cc36c Author: Marek Olšák <marek.olsak@amd.com> Date: Tue Apr 24 17:01:35 2018 -0400 util/u_queue: fix a deadlock in util_queue_finish Cc: 18.0 18.1 <mesa-stable@lists.freedesktop.org> Reviewed-by: Nicolai Hähnle <nicolai.haehnle@amd.com> Feel free to reopen if you are still having problems.
It's still broken for me actually, and reverting the commit original commit works around the issue. Maybe there is something that is specific to my system that is causing the problem.
Scratch that; looks like a manual git build works, but not mesa-9999 in the Gentoo repository. I've tested with minimal cflags too and the problem remains, so I'm not sure what the difference is.
