  1. start a complex scene, mr_serie14_bone_muscle_fat_tendons_ligaments_vessels.xml
    (4 volumes)
  2. move towards the volume (w key)
  3. the screen shows a white circle only

tested on a 840m graphic card, 2gb ram, 512x512 resolution

Thanks. I was able to reproduce it once with the multi-volume scene, but failed two times afterwards. Can you provide your test scene with the assets? Can you please also save the camera position (F10 shortcut) if only the white circle is rendered and then load the scene again and set this camera position.
