Blurry loading screen

Hi, recent versions of Mesa have made this game go from 30 fps down to under 1 fps, and have caused the bottom of textures to become blurry (see attachment). I've bisected it down to commit a86fc719d6402eb482657707741890e69e81700f (enable LLVM by default on x86 and x86_64). I don't know why LLVM causes this but I've verified that disabling it via configure fixes this problem. I now use: 

./configure --prefix=$HOME --enable-gallium-r600 --disable-gallium-r300 --disable-gallium-llvm --disable-gallium-egl --with-state-trackers=dri

I know r300g requires LLVM but are there any reasons to enable it for r600g?

Thanks,
-Damien

Same problem here on HD4850 and 5770, will try to disable llvm when I'm back home.

This may be similar problem to bug 30901, try to remove libstdc++ bundled with HoN.
Comment 3 Damien Grassart 2011-05-26 05:03:02 UTC 
Yes, it seems that was the issue. Removing the libstdc++ bundled with the game fixed the problem as well. Thanks!
