I found this bug ages ago but forgot to report it so here I am.
Create any Geometry (instanced, non instanced, FBX, etc…) and switch to/open a separate Geometry Viewer.
Before you do anything I recommend setting both the Camera Navigation Mode and 3D SpaceMouse Navigation Mode to “Object Mode” (right click anywhere in your Geometry Viewer and they will be your first two options).
By default you will be in Perspective mode, switch to Orthographic by pressing “o” on your keyboard.
Start zooming away from your Geometry by scrolling down your Mouse Wheel, the further you do it the worse the bug will get.
Switch back from Orthographic to Perspective (press “o” again) and your viewer will experience heavy perspective distortion, the more you have zoomed out in Ortho mode the worse the resulting distortion will have become.
This can be fixed at any time by simply resetting your camera position with an Homing or Framing option.
