Comment 2 for bug 1805753

I've also noticed that after disconnecting, if I drag windows to the right, they go off the laptop screen and become inaccessible from the screen.

So it seems it isn't properly detecting that the HDMI is disconnected (from laptop)

This is an extremely annoying and astonishing usability issue.

Expected: on disconnect, windowing reset to normal primary mode, moving all windows back to the active screen

Workaround: opening Displays Settings forces reset
