           Summary: r600g with LLVM enabled makes Heroes of Newerth game
                    unplayable
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: damien@grassart.com

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.

Yes, it seems that was the issue. Removing the libstdc++ bundled with the game
fixed the problem as well. Thanks!
