Psychic powers. ;)

... Actually kind of a side effect from gathering more information to prepare for debugging. I was just drawing in some new objects to try and repeat the problem to make sure it was not due to something like a messed up trimming boundary. I was also trying some variations to see what happens if I moved stuff around, tried larger or smaller things, etc.. just trying to see if there was some kind pattern that could help me to track down the bug.

If I can find a pattern to the behavior then that can sometimes help me focus on a particular area for the bug.

Then if I find something where the bug is not triggered it can also lead to a workaround.
