           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.

The conditions for this failure appear to be related to sync uploads only (with
or without readbacks is, at a guess, irrelevant).  At any rate, commenting out
the test to use a staged upload in this instance cause the missing text(ures)
to reappear.

I'm suspicious that at the end of the big if( use_staging_upload ) block
there's a call to r600_copy_to_staging_texture() in the case of
PIPE_TRANSFER_READ but apparently no equivalent call for PIPE_TRANSFER_WRITE.

Please try again with git master.

Maybe commit d5aadf0d80e8c973ef5cf9d82e97f23f0e3c032b fixed this problem.

I can confirm that this commit fixes the issue in XBMC (Bug 31615).
