Handles are not rendering correctly

Reproduction Steps:
Using this model (rbxm file if you don’t want to take model) and placing it in StarterGui, with all of the Handle’s adornees set to the same BasePart Instance, saving the place, closing and re-opening it, and then moving around with the WASDEQ keys will render the squares in the same position.

Video reproducing the bug:

After all of these I deleted the Part from workspace, and another bug happened:

Expected Behavior:
The squares should not remain on the screen (atleast in the same place) when moving camera.
Actual Behavior:
The squares remain rendered in the same position, until they are Parented to something else and then back to StarterGui/CoreGui.
