Bug ID: 103808 Summary: [radeonsi, bisected] World of Warcraft scribbling all over screen Product: Mesa Version: git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: rankincj@googlemail.com QA Contact: dri-devel@lists.freedesktop.org
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.

WoW continues to run, but UI elements in particular disappear and are replaced with scribbles across the screen, which itself flickers and flashes.
