err:winediag:wined3d_texture_init The application tried to create a DXTn texture, but the driver does not support them.
That's likely bug 14939.
Well, no, that's likely just missing DXTn/S3TC support in the driver. On Debian and its derivatives you can usually fix that by installing libtxc-dxtn-s2tc0:i386, other distributions may have similar packages.
