--- Comment #5 from Zak <[e-mail]> ---
After upgrading wine to 10.20, the game now renders a black screen when
entering the hub with 

01a8:err:d3d:wined3d_debug_callback 081D3448: "GL_INVALID_OPERATION in
glBindBuffer(non-gen name)".
01a8:err:d3d:wined3d_debug_callback 081D3448: "GL_INVALID_OPERATION in
glBindBuffer(non-gen name)".
01a8:err:d3d:wined3d_debug_callback 081D3448: "GL_INVALID_OPERATION in
glBufferData(immutable)".
01a8:err:d3d:wined3d_debug_callback 081D3448: "GL_INVALID_OPERATION in
glBufferData(no buffer bound)".
01a8:err:d3d:wined3d_debug_callback 081D3448: "GL_INVALID_OPERATION in
glUniform1(uniform \"ffp_projection_matrix\"@1 is matrix)".

but I suspect the bug appeared with 10.18, which introduced Vulkan memory
mapping for OpenGL. Will need to retest to make sure.
