Mask bug v2.6.2 for Mac

In any modules where mask is used the circle and oval mask brush feathering only INCREASES with shift scroll wheel in both directions. Even worse there is no way to reset it, even after closing the program the previous size circle or oval will reappear.

This is a major bug, any solutions?

Are you using the official DMG or did you build it from source?

It works as expected only if you use an Apple mouse.

Ctrl+scroll works and only scroll wheel works the problem is only when using Shift+Scroll.
I am using the official DMG. This problem is with all feathering not only in circle and oval. So somehow Shift+scrollwheel is not recognised and I am not using an apple mouse.
