When using the healing brush, the brush size is automatically decreasing as I use the tool. I am on a Mac 10.15.7. The behavior occurs in the current versions of the software, as well as earlier versions. I am also using a Wacom Intuos Pro. I uninstalled the Wacom software to see if that would make a difference, but the problem continues, regardless. Any help would be appreciated!
Sorry to hear that. Does it only happen in Camera Raw? Have you tried using the Brush tool in Photoshop and see if you experience the same behavior? Also, have you tried updating the Wacom drivers and see if that helps?
