Windows 10, version 2004 (19041.113). I understand completely this version, although not supported or released, is VERY close to being. But, it is not released. 
Just updated to Groupy 1.32 beta. This is actually happening in the new Edge browser window. My Taskbar is across the top (Yes, it is).
Wondering if this is a known issue or was supposed to be fixed at 1.30. Thank you!
