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.
