Have you ever experienced the frustration of your desktop application windows unexpectedly rearranging every time you return to your computer from sleep? Imagine the following scenario:

1. Your device (laptop or desktop) is connected to external monitors over a DisplayPort connector. Application windows are placed in certain locations on your screen.
2. You leave your system for some time and your device goes to sleep.
3. You come back and return to your system to wake your device.
4. The application windows have unexpectedly moved to a different location of the monitor (sometimes clustered on one screen).

As a result, you have to re-drag application windows to the original, intended position pre-sleep. This is likely to lead you to feel frustrated because this happens almost every time when your system goes to sleep and takes time out of your productivity.

The technical terminology we use to describe this problem is known as Rapid Hot Plug Detect (Rapid HPD). This behavior impacts DisplayPort multi-monitor setups which results in unwanted desktop rearrangements. We have worked towards mitigating desktop rearrangements when Rapid HPD occurs.
