menues and shadows flicker while repainting

[Vladimir]

Hi,

I have a Java application that repaints a window contents
with a high rate. This causes menus and shadows to flicker
in Windows XP. The effect disappears after the monitor
refresh rate is changed (doesn't matter if it's changed to
a higher or lower value) or even if I press Ctrl-Alt-
Delete and cancel. Does anyone know how this problem can
be resolved without these manipulations?

Thank you.

Draw with back buffering, decrease the update rate, or
only redraw what has changed, depending on what the app is
really doing.
