Weird, while trying to create an example I discovered 2 things:
1: Loading meshes from the binary only works until I save the project (As in, from a temp file)
2: I used the select tool to select the topmost pixels of a 96x96 square and when I released the mouse button, the whole image disappeared.
Here's the tearing I was talking about (only happens with 3D layering turned on):
The blue one is 4 different, rotated objects
