That stopped it from conversion to perfect circles or elongated rectangles, but I still have issues drawing anything with smooth curves. E.g. Here's a side by side just drawing "o's" at varying speeds on witeboard and ziteboard.[0]

To get anything remotely legible on witeboard, I have to be exceptionally slow. Even then, it's not a great result.

Thanks for the tip.

I tried turning off that option and unfortunately it didn't improve things at all.
