Virtual Screens Jumping to Host Screen 1

I am using a Windows 10 Guest on a Linux Mint Host with multiple screens.

I do not use full screen mode because I want access to the Mint Toolbar to switch desktops and run apps in Mint.
I arrange the screens and maximise them. This works well for me.

My issue is that when I leave the PC for a while, the screens all jump onto Host Screen 1, whether the Mint screen saver has kicked in or not.
The Win 10 Screen Saver has been disabled, and I have extended the power settings to not turn off for 4 hours - the screen jump happens over lunch usually less than 1 hour!

I have searched for this in many places - it has been happening for more than one year (through Mint and VBox updates) on two matched screens.
I have added a 3rd screen, and because it is a different layout, I have to rearrange all my windows every time. :?

Please help ...

Mint System:
Kernel: 5.4.0-84-generic x86_64 bits: 64 compiler: gcc v: 9.3.0
Desktop: Cinnamon 4.6.7 Distro: Linux Mint 20 Ulyana
base: Ubuntu 20.04 focal

Update 2021-09-26: Tried xfce - still happens

This was caused by the Mint Host powering down the screens. Under Power Settings ...

Glad you found the problem! (This topic was completely beyond my ability to troubleshoot...)
