Brush mode zooms in unexpectedly at the start of each brush stroke.

I updated Lightroom CC a few days ago and today I am using the masking brush since the first time since the update.  It's kind of a disaster,  in Mask mode, the brush tool zooms in unexpectedly at the start of each of my brush strokes and then immediately zooms back out. This is causing my brush to cut through parts of the image that are already masked. Every click it zooms in and zooms out. 

I am a professor of photography and teach lightroom, so it's not user error!  This is a new bug that only showed up with the new options for Super Resolution and Distraction Removals.  

I do have super-resolution added to the image that I am working on, so I am guessing the bug has something to do with that.   I have to try to click on an an empty area (hard to do when zoomed in) so that the quick zoom in and out doesn't drag my brush through an existing mask. I often have to immediately undo the brushstroke and try again.  It is VERY annouying and time consuming. 

Since I work at a University, my account doesn't even have the option with the "talk to us"  help button. It just tells me to talk to the local administrator. I don't think they can help me since I think this is a software bug!
