It isn't possible to provide any screenshots.

Research direction

Start by reproducing the FancyZones issue on Windows 11 with Shift held while using Totality Apex and IBKR Desktop, and compare them with applications that highlight zones correctly. Investigate how FancyZones recognises these application windows; done means the zones highlight and allow snapping for both reported applications.
