move free difinable screens project from copa-data blog

I tryed to run example project from last blog entry and noticed that when i move form partially out of main window and then move it back into center of main screen some artefacts of redrawing appears on moving window (see attachment). This remainds me some artifacts I see when using World View component. Is there some ability to redraw window manualy or by timer to fix this issue?
