I am having the same exact problem with my laptop connected to 2 monitors (3 screens in total). I am on the latest version of Fences (I purchased it in February 2022) and whenever my screens go to sleep, when I wake them up, all of my fences are shoved to my "Main" display, which I currently have set as Screen 3. I then have to try and restore a snapshot, which doesn't seem to work after this happens. If I unplug my external monitors from my laptop and then plug them back in, the same problem appears to happen (all fences shoved to my "Main" display instead of across my 2nd and 3rd display) but the snapshot restore works in this circumstance.
I'm running on a brand new laptop that is less than 4 weeks old (HP Elitebook 850 G8 i7 w/ 16GB RAM and 1TB ssd) and have all of the latest Windows updates and HP driver updates ( I thought the issue might be related to the Intel video driver so I made sure it was up-to-date), but I can still manually reproduce the problem of all of my fences across all of my monitors going to a single monitor if I unplug and plug back in my screens. And still when my computer screens sleep the problem occurs but it will not let me restore a snapshot at that point.
Any suggestions on what I should do would be greatly appreciated.
