           Summary: [r300g] Flickering user interface in WoW
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r300
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: rankincj at googlemail.com


I have noticed that the user interface in WoW has started to flicker recently:
the more "item" icons (in bags, bank slots or on action bars) that are on the
screen at any one time, the more likely the bug is to occur. 

Some of the writing in the UI may also be corrupt, but the main problem is that
parts of the UI itself disappear and are redrawn very quickly, over and over
again.

I have observed the effect with both my RV350 and my M66GL.

According to git bisect:

363ff844753c46ac9c13866627e096b091ea81f8 is the first bad commit
commit 363ff844753c46ac9c13866627e096b091ea81f8

    winsys/radeon: move GEM domains out of the drivers into winsys

    The drivers don't need to care about the domains. All they need to set
    are the bind and usage flags. This simplifies the winsys too.

    This also fixes on r600g:
    - fbo-depth-GL_DEPTH_COMPONENT32F-copypixels
    - fbo-depth-GL_DEPTH_COMPONENT16-copypixels
    - fbo-depth-GL_DEPTH_COMPONENT24-copypixels
    - fbo-depth-GL_DEPTH_COMPONENT32-copypixels
    - fbo-depth-GL_DEPTH24_STENCIL8-copypixels
    I can't explain it.
