urces when redrawing is required. A passive slider doesn't require a lo=
t of CPU (if at all), but it does when you move it. The more complex the GU=

rawn all the time (like in an oscilloscope). <br>

Hello list<br>
reading everywhere that GUI takes enormous amount of CPU.<br>
More precisely : does a GUI element, say a slider monitoring a signal, requ=
ire lots of CPU in anycase -even when for instance it is invisible somewher=
e deep in a subpatch-, =A0or is it requiring lots of CPU only when displaye=
d in front window ?<br>
