The fake cursor is drawn with glBitmap, and positioned with 
glRasterPos so I can see how there might be a conflict.

I think there may be a simple fix.  Could you edit 
spu/render/renderspu.c and change line 321 from this:

   render_spu.self.PushAttrib( GL_TRANSFORM_BIT | GL_VIEWPORT_BIT );

to this:

   render_spu.self.PushAttrib( GL_TRANSFORM_BIT | GL_VIEWPORT_BIT | 
GL_CURRENT_BIT );
