I had hopes Fences 4 would finally, after years of this issue being problematic, resolve the Fences constantly changing screens if moved to a non-primary display. Unfortunately, not only this matter isn't fixe but it seems to be getting worse. This matter has been going on for years, with posts on this forums going back to 2017 and no-one had escalated it/fixed it. The snapshot restore layout reset process does not work, never did. Any graphical driver change resets the fences back to primary. I got enough. Fences move for no reason on restart.
This app clearly isn't suited for multi monitors. Its not worth it anymore. I'm uninstalling this piece of junk and blacklisting Stardock apps.
