OpenGL issues (DEPTH_TEST) in Serious Sam Classic

[mittorn]

Depth test does not work. Seems to be a bug somewhere in wgl/glx translation layer. Check if depth buffer size translated correctly
SeriousEditor has the same issue
In D3D mode game does not draw anything with such errors:

Mesa: User error: GL_INVALID_ENUM in glMatrixMode(mode)

+1. Depth test is broken for me too. GPU: Intel

Seems to be recent wine bug (3.x)
reports in winehq from previous versions says opengl support is ok

OpenGL mode seems to work correctly on Nvidia. It might be a Mesa bug.
