Bug #: 30168
           Summary: GLSL does not work on ATI-based Macs AND disabling
                    them causes black screen
           Product: Wine
           Version: 1.4-rc6
          Platform: x86-64
        OS/Version: Mac OS X
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: directx-d3dx9
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
                CC: [e-mail]
    Classification: Unclassified

This is a problem on many games, specifically I've experienced it on:
Kingdoms of Amalur: Reckoning
Mass Effect 3

GLSL is on by default, with it enabled the following errors display
continuously:
err:d3d_shader:shader_glsl_select >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION
(0x502) from glUseProgramObjectARB @ glsl_shader.c / 4771

This causes many textures to be semi-transparent/black/stretched crazily

Disabling this setting causes the error to go away, but then you just get a
black screen.

System:
OSX Snow Leopard (10.6.8)
Macbook Pro 15" (2011)
AMD Radeon HD 6750M (although seems the same on all AMD-graphics macs)

I'm hoping there is a simple workaround for someone who knows what they're
doing. Here's a log dump from ME3:
