I accidentally created a virtual desktop today (CTRL-Windows-D).

I noticed that DisplayFusion title bar buttons remained on the new virtual desktop even though the window itself did not. Also, those buttons remained "functional" even though the window itself remained invisible.

Hmm... side question - can you have different wallpapers per virtual desktop?

FYI:
CTRL-Windows-D: Create virtual desktop (unlimited number of)
CTRL-Windows-left/right arrow: switch between
CTRL-Windows-F4: delete current virtual desktop
Windows-Tab: Task swapper that has virtual desktop selector as well (as opposed to ALT-TAB).

From "winver": Windows 10 Version 1709 (OS Built 16299.371)
As for anything beyond that, I don't know unless you can tell me where to look

The buttons seemed to remain longer than that for me. Also, to clarify, it wasn't the full title bar. Just the DF title bar button(s) floating alone.

In any regard, give those latent buttons a press, and you'll see they'll move to accommodate an invisible window as well. I didn't go further than that with my own testing.

Cheers,
Al
