Also, you could try removing the timer call altogether -- maybe it has a
minimum:
def OnSize(self, event=None):
self.InitializePanel()
#self.SizeTimer.Start(50, oneShot=True)
self.OnSizeTimer()

that is odd, but I can't explain it -- perhaps the Paint event is getting
called mixed in with the Size events.... So you get the image re-drawn on
the not-yet-resized buffer. What platform are you on? that may make a
difference.
