I've managed to narrow the source of the problem even further: If I keep all my planet models and remove the stars then everything is still fine with 2 views !!!
=> So I'm on my star model now... this model is a simple geometry with about 110000 vertices, rendered as POINTS... I know I should cut this geometry into pieces, but could this really explain the problem I'm facing now ??
