I know I haven't shown myself around these parts and probably still a public enemy over me losing all control of myself (and other stuff) due to reasons... However all of that aside for obvious reasons and this appears to be an issue I don't know if it's been reported before or slipped through the cracks:
Here's what happens after what I said happened in the title: I place a box, cylinder and a shapebox for example:

The longer box is an actual box and the highlighted cube is a shapebox

This is some proof that it's not a visibility thing either.
Then I set the model texture to something else other than "None" this happens:

Doesn't the bit with the box seem familiar?
Drum-roll...
That's Marc
