New Image trace in 29.0

Not sure if this is the right place to put new thoughts on the update but I'll include one critique I have.

I am not enjoying the new Image Trace. I have an image of B&W half tone dots and have spent hours fiddling with the new Image Trace settings trying to get the circles to be expanded into vectors.

However, whenever I Image Trace, the circles lose their perfect shape and morph into oblongs. I was confused as to why this was happening, as previously I had done it with zero difficulty. After hours of playing with the paths, corners, noise, and all the other Image Trace settings, I had finally re-downloaded v28.

Lo and behold, easy Image Trace, with my circles remaining circles, not oblongs.

If I am missing something, please advise, otherwise I much prefer v28's Image Trace function.
