Upgraded a Fences 3 install to Fences 4, and after restart the saved snapshots loaded into 4 are stretched out horizontally.  They extend past the left-border of the left-monitor, with one fence now completely offscreen having been pushed by its neighboring box. 

Reloading the saved snapshot has no effect.  Had to uninstall Fences 4 (after also disabling it from starting up due to file in use error preventing uninstall to complete and fail out) to reinstall Fences 3 with saved snapshot files.

This is on a multiple monitor setup (two 1920x1080 displays side by side in landscape) running latest version of Win10 Enterprise 21H2 build 19044.1348 and Intel Iris Pro Graphics 580.
