--- Comment #2 from Chris Rankin <rankincj at googlemail.com> 2010-07-06 12:33:59 PDT --- I tried running WoW with the RADEON_DEBUG="tex" option, and noticed that many textures were in formats: dxt1_rgba dxt3_rgba dxt5_rgba And so because I am also using libtxc_dxtn070518.tar.gz, I moved the libtxc_dxtn.so object out of /usr/lib and tried running WoW again. And this time, the textures were all fine... right up until WoW crashed a few seconds later.
