[Wine] Re: Disabling S3TC support for Wine 1.1.14 How do I patch?

[Thunderbird]

Nope that key won't work for direct3d. The easiest way is to just comment the following line in wined3d/directx.c:
    {"GL_EXT_texture_compression_s3tc",     EXT_TEXTURE_COMPRESSION_S3TC,   0                           },

So add "//" in front of it or remove the line.
