3D rendering makes whole screen glitch

When I’m in Segmentation Editor and I press “Show 3D” the screen glitches between something like this image and normal. When I have all of my segments deselected with Show 3D on, the screen is also normal. I’m not really sure what’s going on. I am using V 5.10. A team member added new segmentations since the last time I opened the file. What do you think the problem could be? Has anyone seen this before? Thanks.

To explore, I would try:

  • zoom way out or way in
  • see if you can narrow it down to a particular segment
  • turn on or off “Shadows visibility” (in pushpin menu on 3D view)
  • try toggling between orthographic and perspective view (in pushpin menu on 3D view)
  • in the Segmentations module, try removing and recreating the “Closed surface” representation
  • Try turning off surface smoothing in Segment Editor module (in dropdown on “Show 3D” button)

The results can help narrow down where the problem might be (or might make it go away).
