actual master (1aac94dc16abbc1ff5b54a4cafd61afd788bbfa5)
works visibly, but gives many gl-Errors, and sometimes a 'soft' crash
(see screenshot)

I observed these gl-Errors ONLY IF bundle is set to be visible.

Visibility or even existence of the fiducials (which are planar figures)
does not seem to produce errors.

Many times this error:

2454:#33.703# [VtkError] ERROR: ERROR: In /home/mhettich/MITKsuperbitch/ep/src/VTK/Rendering/OpenGL/vtkOpenGLProperty.cxx, line 646
2455:vtkOpenGLProperty (0x5b57c90): failed after Render 1 OpenGL errors detected
2456: 0 : (1281) Invalid value

Sometimes:

Once and soft-crashing:

420:#9.653# ERROR: An error occurred: deque::_M_range_check
