Summary: C&C3: Malfunctioning shaders
           Product: Wine
           Version: CVS
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

With the most recent wine from git (last wine I tried that didn't show this
problem was a git shortly after .36) and when having enabled shaders
(UseGLSL=enabled),  when trying to play a skirmish (and probably when trying to
play any type of game) it hangs with a black screen.

In the output of wine there are some new messages that haven't appeared before.
 These two are the first:

fixme:d3d_shader:print_glsl_info_log Error received from GLSL shader #536870913:
"WARNING: 0:1: extension 'GL_ARB_draw_buffers' is not supported\n"
fixme:d3d_shader:print_glsl_info_log Error received from GLSL shader
#2147483649: " Link successful. The GLSL vertex shader will run in hardware. The
GLSL fragment shader wil
l run in hardware."

There are several more including errors, which can be read in attachment.
