           Summary: UI Fonts in Blender are not visible with recent Mesa.
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: FJ.Whittle@gmail.com


All user interface text in Blender 2.55(alpha) and smooth fonts variations of
Blender 2.49 is rendered invisible by recent build of Mesa on the r600 gallium
driver.

Prerequisites: Mesa current git, any blender 2.55 alpha version including
latest svn

Steps to reproduce: Run blender

Expected outcome: Full user interface with fonts correctly rendered.

Actual outcome: No user interface text visible.

    r600: fix my pessimism about PIPE_TRANSFER_x flags

as the culprit.  Rebasing to latest mesa git (master) with this commit reverted
works as expected.
