I’m running XFCE on Linux and I’ve run into a strange problem : I can only see one window at a time.
If I open several applications (e.g. Firefox, Terminal, VScode,...), they all appear in the top panel taskbar, so they are running. But on the desktop, only the active window is visible. As soon as I click on another window in the taskbar, the previous one disappears from the screen.
How can I make XFCE display multiple windows on the screen at the same time, instead of hiding all but the focused one?
