You need (32-bit) libtxc_dxtn for s3tc support with r600g.
Thanks a lot for the hint, but I have it installed for sure. Otherwise I'd get the "Mesa warning: couldn't open libtxc_dxtn.so, software DXTn compression/decompression unavailable" as I'm running with MESA_DEBUG=1
Any further ideas ? You know where the internal- and gl-format are associated for the surface ? Or is it the result of some conversion function ?
