OpenGL renderer string: AMD BONAIRE (DRM 2.50.0 / 4.13.13, LLVM 6.0.0) OpenGL core profile version string: 3.3 Mesa 17.4.0-devel (git-4b0dc098b2) Now that Fedora has upgraded to libdrm-2.4.88, I have discovered that World of Warcraft now has huge screen corruption with Mesa-git. A git bisect has identified this commit as the culprit: 4b0dc098b2561c07c59f7dab2813640a25789bf1 is the first bad commit commit 4b0dc098b2561c07c59f7dab2813640a25789bf1 Author: Marek Olšák <marek.olsak@amd.com> Date: Thu Nov 2 00:00:53 2017 +0100 gallium/u_threaded: don't map big VRAM buffers for the first upload directly This improves Paraview "many spheres" performance 4x along with the radeonsi commit.

Can you upload an apitrace?

There's some initial chaos when you start replaying this trace, but I think the most relevant artifacts (from this bug's perspective) occur right at the end.

Marek pushed this fix: https://cgit.freedesktop.org/mesa/mesa/commit/?id=b5444877c0820b7848c07d1bc4e9a706f90894a5 I've just tested it with The Witcher 3 in Wine, and flickering is gone along with performance drop!
