Well, there are different kinds of processes involved into the lag. If we try
to limit the lag definition for this bug to "the lag of the outline that
happens when hovering the stylus over the canvas surface and that is
proportional to the display resolution", then this kind of lag is fixable.
The solution to this lag is to finally implement partial updates for the openGL
canvas. That is now possible thanks to Qt's internal widget buffer that caches
the canvas.
