Same issue with 23H2 I also am seeing a problem with general saving of fences. I can create a new fence, save it and it remains on reboot. But the sizes are never saved and revert on reboot each time.
Going to test here today, but you can fully disable the new Windows 11 taskbar and start menu and restore the Windows 10 version via registry. I am unsure if MS will allow this tweak to persist in future releases but for now you can do it following these instructions: https://winaero.com/how-to-restore-classic-start-menu-in-windows-11-and-get-back-live-tiles/
From just a day of testing, Start 10 is only working on secondary monitors with Displayfusion in Windows 11, not the main monitor.
Great! Any updates?
+1 Happens on all windows 10 devices I have tried it with. (2 desktops and 3 laptops)
