          Priority: medium
            Bug ID: 84156
          Assignee: dri-devel@lists.freedesktop.org
           Summary: Half of lighting gets broken in older apps
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: smoki00790@gmail.com
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/Gallium/radeonsi
           Product: Mesa

This is from old bug 77785 and about old games where seems like GLSL is not
used. In examples i can mention it happens when truck/vehicle turn on lights.
Useful apitrace from 18 WoS: Pedal to the Metal game - it is OpenGL game
running under wine:

 The same issue i found that can be reproduced is with 3DMark2001
http://www.futuremark.com/benchmarks/legacy (which is mostly for benchmarking
DirectX8 features. So it happens too in 'Car Chase' test, but only when wine is
used with UseGLSL disabled.

 After commit radeonsi: force NaNs to 0


http://cgit.freedesktop.org/mesa/mesa/commit/?id=2150db4d5daad3781876254d2b440367afd756cd

 Rendering changed partially, at least truck is no more black.

Whether it works with fglrx is irrelevant for this bug report. Does it work
with radeonsi?

 No it does not work, so i guessed it is irrelevant after 2 years of no one
else commennted on it.
