Can not see the brush size with photoshop

[#1]

I work on a computer Mac. When I use control+alt while scrolling the mouse with the brush tool and  usually, I see in red the size of my brush. I scroll and that ajust but, I can not see the red zone since I've update photoshop.

Personally I expect that this will be addressed »soon« but there are no guarantees about a timeline even for acknowledged bugs.
