Alt+Right Click Bug - (Changing Brush Size) Since last update (21.1)

Hi.

Since Last update, I came across a very annoying bug that occurs about 80% of the time.

When I use Alt+Right in order to increase or decrease my brush size, most of the time, my brush size doesn't change the way I want and goes huge, and sometimes doubles.

Example :"I'm on a 5px brush size, i use Alt+Right Click, and drag to increase it to 15px. When I release my Alt+Right Click, my brush size goes to 1200 px. I do it again And try to decrease, It goes 2457 px."

Also 50% of the time it just goes 1px brush size.

How Can I fix this please ?

I'm using a Huion GT220.
