I found out that ContinuousRepaint is to performance hungry for my situation, so i want to use triggerRepaint() instead. (with less fps, setSwapInterval doesn't fit )
But if i look at the source, it looks like triggerRepaint() also refreshes the componentBuffer for the child-overlays.
Would be nice if there is an option triggerRepaintNoComponentBuffer() which only only does repaintEvent.signal() (without needsUpdate = 1; )
thanks
