The displayed size of the brush (under the cursor) is much bigger, then the actual size of the marked area. For example when I select a brush size of 60, I get a correct marking with radius 60, but the red circle under the cursor has a radius 2-3 times as much (I would gues around 180) , which doesn't help in precise cursor manipulation.
(sorry for low quality photo, but screenshots doesn't capture the cursos so the red circle is not visible on screenshots)
