--- Comment #2 from Alexandre Demers alexandre.f.demers@gmail.com 2011-06-09 19:58:59 PDT --- Since it only happens when I use Diablo 2 with Glide, it is probably related to the Glide to OpenGL wrapper. If indeed the extension is not supported in r600g, then it is related to the application, thus the wrapper. I could try with a different wrapper (instead of GLIDE3-to-OpenGL-Wrapper/svenwrapper).
