           Summary: [r300g] Latest Mesa breaks Wine - "Bad vertex format"
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: rankincj@googlemail.com


Trying to run Wine against the latest Mesa causes this error message:

r300: Bad vertex format r32g32b32a32_sint.
err:module:attach_process_dlls "opengl32.dll" failed to initialize, aborting
err:module:LdrInitializeThunk Main exe initialization for L"H:\\World of
Warcraft\\Wow.exe" failed, status 80000101

The following commit seems to be responsible:

    u_blitter: add integer clear support

    We need add a new set of fragment shader variants, along with new vertex
    elements for signed and unsigned clears.

    The new fragment shader variants are due to the integers values requiring
    CONSTANT interpolation. The new vertex element descriptions are for passing
    the clear color as an unsigned or signed integer value.
