First I would update to the latest GIT version as a LOT has changed in the Wine's OpenGL implementation recently. Second what video drivers are you using? In short when programs contain a 'small' 3d view rendered using either opengl or direct3d, we render to an X window which is made offscreen using X Composite. The contents of this window is then copied to the right location.

The problem is that this method isn't supported on all video drivers yet. Basically it is the same functionality which is needed to get a glxgears window to render on a compiz cube.
