P: No red preview when changing brush size

Same problem here!
Feel free to fix, smart hacking-humans at Adobe!

Also, when you press opt (mac), it doesn't show the sample ring for choosing the color...problem

I'm also having this issue. Super frustrating. I haven't been able to troubleshoot it. 

Same problem in photoshop 22.0.1

Brush size and Hardness overlay (red), not showing...annoying 

Same problem, in version 22.0.1 brush red hardness overlay not showing. 

Here the same problem 😞

Yes, same issue here. Another thread on the same subject, just in case someone wants to merge them:

https://feedback.photoshop.com/conversations/photoshop/brush-size-and-hardness-overlay-in-2201/5fb4c167762a722b89c6143b

I'm experiencing this issue too - just updated from 22.0.0 to 22.0.1, and the red overlay for size and hardness is gone. Please fix it!

(I'm using Windows 10, and my "Use graphics processor" checkbox in Prefs/Performance is ticked)

ja, bei mir wird sie auch nicht angezeigt

Yep, I can confirm that... tried everything and the red hardness overlay still not showing.

Also, for healing brush if you resize it using 'alt + right click + mouse drag' it doesn't display as the new brush (if you changed the angle and roundness), it displays as the default brush (the default round one).

I just went back for now to version 22.0.0 where everything works.
