Package: libtxc-dxtn-s2tc0
Version: 0~git20121227-1
Severity: normal

Dear Maintainer,

I try to run Counter-Strike: Source via steam and it complains about no s3tc
support:

  This application requires either the GL_EXT_texture_compression_s3tc, or the
GL_EXT_texture_compression_dxt1 + GL_ANGLE_texture_compression_dxt3 +
GL_ANGLE_texture_compression_dxt5 OpenGL extensions. Please install S3TC
texture support.

despite having libtxc-dxtn-s2tc0 installed and glxinfo reports the extensions
are available:

I don't have enough expertise to develop an open test case, but I just thought
I would report it here. Please let me know your thoughts on why steam/CS:S is
not properly detecting s3tc support.
