             Bug #: 45277
           Summary: [bisected] Shading not working properly in Heroes of
                    Newerth
    Classification: Unclassified
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
        AssignedTo: mesa-dev at lists.freedesktop.org
        ReportedBy: damien at grassart.com


Hi, a recent commit seems to have broken the fog of war shading in Heroes of
Newerth (with my Radeon HD 6850 at least). You can still see the players pop in
and out of the fog, but the entire map is shaded darker where there is no
longer any light/dark distinction between the parts of the map that are visible
and the parts that aren't.

I've bisected the issue and found the first bad commit to be:
bc1c8369384b5e16547c5bf9728aa78f8dfd66cc st/mesa: do vertex and fragment color
clamping in shaders

I've confirmed that building Mesa with the previous commit
(c2e2b58a58880c9b9f189fc154205e99144e9502) does fix the problem.

If you need to test it, the game is a free download from
