Description Henning 2023-09-19 16:02:39 UTC

This is a graphical bad behavior I think.

1. have all panels loaded and be there
2. connect a second display that itself has a different panel

What happens:
ALL panels reload, even those on the main display that stay the same

What should happen:
No blinking. First check if the panels actually change their position, and if not dont reload them. If they change, do the blinking disappear-reload thing.

I am not sure if this is how panels and displays work on Wayland, as a big display and everything changes. But panels that stay the same should never reload, at least under default settings where the main display stays the main one, like on a Laptop.

Are you still able to reproduce this at all in Plasma 6.1.4 or later?
