            Bug ID: 101969
           Summary: Massive graphics corruption with World of Warcraft
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: rankincj@googlemail.com
        QA Contact: dri-devel@lists.freedesktop.org

World of Warcraft's login screen has become jumbled garbage with the latest
Mesa from git. I don't recognise anything as being rendered by WoW, although
there are elements from other applications and windows dancing all over the
place.

I have performed a git bisect, and have identified this commit as the cause:

Mesa describes my setup as:
