Fair enough, I haven't looked at contributing myself so I was not aware of the policy. I do think it might still be worth trying to reach out to their team to see what their thoughts are about the issue you experienced.

I'm sure it could be an uphill battle, but something like this might warrant a toggle-able "debug-friendly" mode that wouldn't be as concerned with performance. I could image possibly extending this principle to make repaints happen much more often, possibly even with a deliberate short pause after each repaint (which you might have already done) to avoid super fast jittering confusing a student's path to understanding loops or the speed of computations allowing them to hide bugs in a string of instructions that don't have one of these wait commands or "critical points" in execution to force a repaint to help them understand the current state.
