On my Radeon HD6950, War Thunder crashes after logging in to the game,

if using LIBGL_DEBUG=verbose and MESA_DEBUG=1 when starting the game, it spams
the following in the console:

Mesa: User error: GL_INVALID_ENUM in glTexStorage2D(internalformat =
GL_COMPRESSED_RGBA_S3TC_DXT5_EXT)
Mesa: User error: GL_INVALID_ENUM in glCompressedTexSubImage2D(format)

and a couple of the messages are a bit different:

Mesa: User error: GL_INVALID_ENUM in glTexStorage2D(internalformat =
GL_COMPRESSED_SRGB_ALPHA_S3TC_DXT5_EXT)
Mesa: User error: GL_INVALID_ENUM in glCompressedTexSubImage2D(format)


Using Fedora Rawhide, Mesa 17.3.0-devel, LLVM 6.0.0, packages from che COPR
repo.
