Ghost window with KDE Connect

How to reproduce:

1. Install/start/configure KDE Connect
2. Open “Slideshow remote” (on phone)
3. Enable the pointer (tap & hold)
4. Besides the overlay window used to draw the pointer (which is floating), there appears to be another “ghost” window allocated in the layout; disabling the pointer makes it go away
5. Enabling the pointer again, move the overlay window (super+drag) so it remains floating but is no longer maximized; the ghost window remains
6. Disabling the pointer now makes ghost window stay there despite overlay window being gone
7. Restarting qtile (e.g. qtile cmd-obj -o cmd -f restart) makes the ghost window go away again

Note: this seems to happen on all layouts but it is easiest to observe in the monadtall layout with one other window open.

The expected behavior is that the ghost window never exist in the first place (step 4), although it is also unexpected that it should linger behind after disabling the pointer (step 6).

Additional info:

• qtile --version: 0.20.0
• python --version: Python 3.10.2
• OS: Arch Linux
• Window system: X.org (with picom as compositor)

Yup, now with commit d55c4390e95850bf66c0333e1773444b3539e97d the _NET_WM_STATE problem has also been fixed. Thank you for your help!
