Description Germano Massullo 2023-12-12 10:57:39 UTC

setup: laptop with 2 external monitors. Wayland session on plasma-desktop-5.27.9-1.fc39.x86_64, QT 5.15.11
I had multiple windows spread all over the various monitors. At a certain moment I disconnected the external monitors, and the applications that were running on those monitors disappeared. They are still shown in the plasma panel of the laptop screen, but if I click on them they do not appear

If you plug the screen in again, do the missing windows re-appear?

Is this experienced on Wayland, or X11, or both?

I could not try since at work I use many shared desks with multiple setups, so when I experienced the problem I was too far from the office where I was using the two screens setup.

> Is this experienced on Wayland, or X11, or both?
I experienced only on Wayland cause I am no longer using X11

Oh, I know what this is.
