           Summary: [regression glsl r300g] Heroes of Newerth slowdown
                    after glsl2 merge
           Product: Mesa
           Version: git
          Platform: Other
               URL: http://www.heroesofnewerth.com/download.php
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: sa@whiz.se


The game Heroes of Newerth (reproducible in the menu with the client) is slow
as molasses after the glsl2 merge. 

Both the game itself, and normal procedures in X while the game is running
(e.g. moving windows around) is noticeably laggy. CPU usage is still low, so I
guess something is keeping the GPU busy?

This bug have not been bisected, only confirmed by trying the commit
immediately before the merge (15a3b42e) which is fine, and the commit with the
glsl2 merge (6c03c57) where the problem is apparent.

This is most likely the same slowdown I noticed in the game Savage 2 (bug
28517) but I'm filing this separately to be sure.
