Forums -> UltraMon™ -> Cloning broken after display sleep mode in W10

By default my displays go to sleep after 10 min. When I move the mouse the display that was formerly flipped-cloned is in the extend mode (unflipped).

The primary (source) display is flickering, windows are showing twice once flipped once normal. The mouse leaves traces.

When I hit the windows key the start menu opens and flickering stops. I can then log out and log in again and the problem is gone.

How to avoid this?

Do you have the latest UltraMon version, 3.4.1? For me this works fine on Windows 10 version 21H1.

I use Ultramon 3.4.1. Windows was 20H2 but after an upgrade to 21H1 nothing changed.

I think it has to to with wake-up speed. The primary display takes about half a second longer to wake up than the flipped display.

When I define the flipped, faster display as the primary and clone the slower one the issue does not occur.
