After testing for much longer and inserting an extra InvalidateRect, it appears
that this bug is occurring for the same reason that many of the other drawing
issues occur. I'll try to explain what I'm seeing:

When a window has been overlapping something which can repaint itself, but the
top of the window is not equal to or higher than the upper line of the
component it obscures, moving the window to the right will leave a grey hole.
When the top of the window DOES equal or sit above the top of the underlying
component, the hole to the left caused by moving the upper window to the right
is invalidated and redrawn. I am now trying to find the code where this occurs.
I think it is GDI related but I'm not an expert yet.
