email form.5.0.00 Beta feedback - Deform brush UI is broken
The reticle for the deform brush displays incorrectly on the Mac (M-series) version of the 5.0.00 beta.
The brush only deforms using the innermost circle. You can still adjust the brush stiffness, but the double circle reticle no longer works as a guide for the stiffness of your selection.
