Resizing Brush disappears and doesn't update realtime 25.1

It's the little things. I feel really bad for the adobe programming  team. The CEO getting millions and millions in bonuses for unCreative Cloud, and  the programmers get annoyed cusotmers.

Adjusting the size of the brush shouldn't cause any problems, yet it does. It doesn't show all the time, if flickers away during the size change, it sometimes shows.
