I'm not sure whether to describe this as a flicker or rapid flashing; probably what is happening is that the window is being redrawn continuously as fast as possible. The visual effect is like a fast strobe.
I don't explicitly use any pack() methods at all, but I'll take a look and see if that's a possibility.
