           Summary: [r300g] Heroes of Newerth slow and corrupted with
                    libtxc_dxtn.so
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: drakkk at centrum.cz


I wanted to try compressed texture support with r300g so I installed 
libtxc_dxtn.so and I got some nice improvements (for example in Neverwinter
Nights textures looks many times better). However in Heroes of Newerth (HoN)
there is big slowdown in menu and while in game it is so slow it almost looks
like frozen and there is massive corruption.

Terminal output:
radeon: Bad CS, dumping...
VENDORID:DEVICEID 0x1002:0x71C5
0x00001007
0x00000004
...
tons of similar hexadecimal output
