Precisely the idea. If the window manager is trying to show the window
contents while dragging, then the window is being send many redraw
commands - I imagine Mbus can't keep up. Not using opaque windows when
dragging should eliminate this.
I can't comment on whether this would effect the vic or not - and I'm
definitely not the definitive source for information on how the rat
operates - this was just an idea for the problem you were reporting.
