According to glxinfo you're not using hardware acceleration anymore but the
llvmpipe software rasterizer. Though I was seeing the problem with that as
well.


Anyway, as described before, the problem basically looks like the game creates
the GLXPixmaps for the characters without an alpha channel, and then tries to
use them as textures with alpha blending. This can't work.

Feel free to reopen this report if the problem persists after the above issue
has been addressed in the game.
