Recently I've been having problems with Alice where, whenever I try to edit an Alice world, everything will glitch up and appear in places where it shouldn't be. It's still possible to edit the world and run it normally, but these glitches make it very difficult to see what I'm editing, which is bad.
This problem has been confirmed to happen on at least two different computers. Both of them run Windows 10, which I thought may have been the cause of the issue, except that one computer had been running Alice on Windows 10 for months with no issues until just recently.
Here's an example of what the problem can look like.
