You say that’s using a zoom factor < 1. Don’t you want the zoom factor set > 1 for hi-res displays? Setting it < 1 makes things smaller, but you want them larger when in a hi-res display, right? We set ours to 2 for hi-res situations (via a menu item the user can select, if they don’t like how small our plug-in appears on their hi-res monitor with the default zoom factor of 1).
