I've noticed it on my laptop which has very slow graphics, on Debian squeeze
(6.0.6, fresh install) :
I open the magnifier view. I set the image size very small, like 10x10.
I choose the discontinuous freehand tool and a single pixel brush.
I draw just to the right of the image edge : the mouse cursor gets choppy and
starts lagging behind until it catches up the mouse movement.
Strangely, with a user brush, this behavior doesn't happen.
It also doesn't happen if the image fills the same space, so it's not the
normal "cumulated rectangle".
When I do the same test on my usual machine (12-year old desktop with AGP 2x
videocard), it doesn't slow down, but CPU usage raises from ~10% to 40%.
Problem must be present in older versions of Grafx2 already.
