Comment # 2 on bug 55445 from Sven Arvidsson

This might be a bug in the game itself:

 Mesa: User error: GL_INVALID_OPERATION in glCompressedTexImage2D(invalid width
or height for compression format)

If so, it isn't clear to me why it doesn't happen on the proprietary drivers as
well?

The bug should probably be reassigned to Mesa core as this seems to happen with
all Mesa drivers.
