[gasensorX]

What Happened?

The F11 shortcut key causes the maximize/unmaximize button to fail. Double-clicking on the title bar also does not restore. The only way to recover is to press F11 again. Double-clicking on the title bar also does not restore. The default maximization shortcut is Super+Up. I can't figure out where this F11 shortcut came from.

Steps to Reproduce

1. Open a Terminal.
2. Press F11.
   At this time, the maximize/unmaximize button is disabled. Double-clicking on the title bar also does not restore.

Expected Behavior

At any time, it should be possible to maximize or exit by double-clicking on the title bar. Or press super+up

F11 is for "full-screening" the app, which is different from maximising and usually results in the headerbar disappearing. The other difference is that the app window overlays the wingpanel and dock when full-screened but not when maximised. It is normal for full-screen to be reversed by pressing F11 again. Some apps (e.g. Chrome) also provide some other way of reversing it.

This is really a window manager issue as it affects any app that keeps its headerbar when full-screened. For example Code has the same issue. Some apps, for example Files, simply disallow full-screening as the headerbar is essential. That is probably the simplest solution here. There is no particular advantage in full-screening a terminal compared to maximising it.

On further thought a less invasive solution is to hide the header decorations when full-screened.
