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: [email protected]
Reporter: [email protected]
QA Contact: [email protected]
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

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.
