Unluckily I have had no success so far. glFinish is in OpenGL.GL but the OpenGL module is not directly used. They use wx.glcanvas.GLCanvas and with it GLContext. Obviously everything works and nothing happens.
Using the OpenGL Profiler I found that I get 2 GL Contexts. One with a bunch of actions and one empty. So maybe VTK fails to get the wxPython GL Context, creates its own and the empty wx context is displayed.
