          Priority: medium
            Bug ID: 55448
          Assignee: dri-devel at lists.freedesktop.org
           Summary: [ColorTiling2D] R600 BARTS radeon: The kernel rejected
                    CS and graphical corruption with tropics
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: maxijac at free.fr
          Hardware: All
            Status: NEW
           Version: git
         Component: Drivers/DRI/R600
           Product: Mesa

I spotted this issue with unigine-tropics. The unigine window is all garbled,
even the loading screen.

Happens whenever I set the DDX to ColorTiling2D "on". When set to off, it
works.

I have the latest DDX & mesa of the time I'm posting this report
for mesa it is 2.1 Mesa 9.1-devel (git-66159f9)
for xf86-video-ati : e8cb0b721e6ea251f85c799ca0563bfa59a2d37c
Linux 3.5.4

I'm using the LLVM compiler but with R600_LLVM=0 I have the same thing

Unlike similars reports about the kernel rejecting CS, Glxgears and others
random GL games don't have problems. Heaven is working correctly.

If I have to bisect, tell me what, the DDX or mesa ?

I'll post a screenshot.
