Thanks to everyone for the feedback.

I think I might have found out why I am the only one seeing the redraw
problem. If I have "Show window contents while dragging" set to false
... I see the redraw problem. If I set it to true ... no redraw
problem.

Can anyone confirm this?

To change the setting:
- Open the "Display Properties" (right click Desktop, then
"Properties")
- Switch to the "Appearance" tab.
- Click on the "Effects" button.
- Uncheck "Show window contents while dragging".

Yes, see the problem now. Amazed it hasn't been seen before now, bearing in
mind it is easy to reproduce if you run with "show window contents while
dragging turned" off.

The interesting thing is that it appears to be because no repaint message is
being sent, although there appears to be an invalid region. Try moving the
mouse over the pin when it happens, and the display will refresh correctly.
Hovering over the pin, so its state changes to hot, only invalidates the
rectangle within which the pin is displayed, so this suggests there is an
invalid rectangle for the damaged area from the resize, but that no paint
message is being dispatched.

Thanks for the bug report.
