Hi
Solved
It Was the SoOffscreenRenderer or better the functions
  SoOffscreenRender::getMaximumResolution();
  SoOffscreenRender::getPixelsPerInch(),

These to seem to create a new XVisual everytime they are called
So when calling them in callback functions too they rapidly use up the 
number of possible XVisuals without freeing them afterwards.

Solution:
  set Offscreen Renderer to RGB_TRANSPARANCY in order to make sure that 
 the maximum Resolution returned is related to the Render Mode using up
  most space. Than query the max resolution and DPI and save both in
  member variables  :)
