Comment:

 I have what appears to be this same error, in R1/alpha3 and in r43768
 (gcc2hybrid, VirtualBox 4.1.6 on Windows XP SP3).

 Steps to reproduce:
     1. Open the Chart Demo.
     2. Set Display to DrawBitmap.
     3. Now set Display to DirectWindow.
     4. Set Animation to e.g. Slow Rotation.
     5. Drag the Chart window around while the animation runs.

 Result:
     The initial star layout, from before the animation started, is
 overlaid on top of the animated stars. These "frozen" stars are erased one
 by one as the animated stars pass through them, but dragging the window
 causes them all to reappear.

 Expected:
     The animation should continue undisturbed as the window is dragged.

 Note that this only happens if DrawBitmap is selected before switching to
 DirectWindow. If I set Display to DirectWindow immediately after starting
 the program, there is no problem.
