Camera Raw: 13.1 right-drag to change healing brush size stops working
In Camera Raw 220.127.116.118 in the Heal panel after the first click to heal, dragging with the right mouse button down no longer changes the brush size. The horizontal double arrow cursor is still displayed, but dragging left or right has no effect.
Moving the size slider, or simply clicking in the numeric field to the right of the size slider, restores normal operation. However, after the next click to heal, right-dragging stops working again.
In Camera Raw Preferences > Performance, I selected Use Graphics Processor: Off, but this didn't help.
