Subject: [Bug 43504] New: tex2D() artifacts (tiling related?) on AMD RV670
Date: Sat, 03 Dec 2011 21:12:15 +0000	[thread overview]

             Bug #: 43504
           Summary: tex2D() artifacts (tiling related?) on AMD RV670
    Classification: Unclassified
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: kam1kaz3@gmail.com

Screenshot showing problem

This is what I'm doing:

1) render scene to render target texture A
2) render quad on screen to show RTT A data

When on the second step, I am using a fragment shader that calls tex2D() to
retrieve the RTT color data, however I get artifacts as shown on the attached
screenshot.

Whenever I restart the application, I get different corruption. I'm not sure
the problem is when reading from the texture, or writing on it.

If I output colors without using tex2D() it all works fine.
