          Severity: normal

Hi,

this is my first bug report, so feel free to point me in a different direction
if necessary please. I am getting a flawless 30+ fps on one of the tutorial
maps without any graphical glitch. However on a different map, there are heavy
texture issues. Please see: http://youtu.be/wHLVaa5aTmA 

Last few lines from dmesg after gameplay:

I tried running Dota2 with
R600_DEBUG=noinvalrange %command% -console
R600_DEBUG=noinvalrange,nodma,nocpdma %command% -console
R600_DEBUG=nodma,nocpdma %command% -console

...neither helps. I don't understand why 68451 has been marked as fixed though.
I'll retry this weekend with 3.14rc2, unless someone advises on what next to
try out.

I've compiled the latest kernel from GIT (3.14), and the texture corruption is
gone.

See comment 48 in bug 68451 for an explanation about why it was marked as
fixed. In short, the original bug (identified problematic commit on given
hardware) has been fixed. The other reports must be treated as different bugs.
