Blender Version
Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-04-03 16:32, hash: rB8681504f0612
Worked: (newest version of Blender that worked as expected)

Short description of error
By adding a follow path constraint and choose a bezier curve as the target, the camera already jumps away by a fair amount. The position values remains unchanged though.

When you now go into camera view, and start to navigate in the camera view, be it move rotate or zoom, then the camera jumps away with every navigation step until it reaches nand.

Exact steps for others to reproduce the error

  • Open Blender
  • Add bezier circle
  • Add Follow Path constraint to the camera
  • Choose the Bezier circle as the target. This is the first position jump
  • Now go into camera view
  • Turn off Lock Camera to view so that you can navigate in the camera view
  • Move the camera view by a small amount. You will notice that the ground grid will vanish. The location of the camera changes dramatically. Up to the point where you reach nand in the location values of the camera.
