Summary: Neverwinter Nights 2: outdoors textures sometimes all
                    white/gray
           Product: Wine
           Version: 0.9.54.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2

        ReportedBy: [e-mail]

When playing Neverwinter Nights 2, version 1.11.1153 (no expansion pack),
sometimes in outdoors environments all textures are white or gray, making
navigation fairly hard.  Apparently this occurs only during the daytime.  I've
attached a debug log from me starting the game, loading a saved game exhibiting
the problem, wandering around for a minute, and then exiting, with debug
options: warn+all,debug+all,err+all,+trace.

Some relevant-looking lines that are repeated very frequently are:

warn:d3d_shader:IWineD3DVertexShaderImpl_CompileShader Swizzled attribute
validation required an expensive comparison

fixme:d3d_shader:shader_glsl_select >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION
(0x502) from glUseProgramObjectARB @ glsl_shader.c / 3226

Especially the second.  But what do I know.  :)  If there's anything else I can
do to help (screenshot? different debug options?) please say.

"The outdoor setting that was used in many of the towns and villages had light
problems. The problem seemed to arise at daytime, and seemed to be a result of
incorrectly handled light effects. It resulted in a screen that was too bright,
often so bright that nothing at all could be seen. The only remedy was either
to wait for the night to kick in or to try to navigate using the map which was
really annoying."
