For me, when I touch it with the terminal open… the terminal window disappears. The keyboard stays up and swiping does not remove it. If I then touch the “square” (lower left) which usually pops up minimized apps, nothing happens. Shortly the desktop goes black and it tries to restart the desktop from the blinking cursor in upper left, which then gives way to the splash screen. But unfortunately, it fails. I end up with a non-responsive black screen which I then have to power cycle.
You referred to the keys as panel buttons, as in “the panel”? If so, is it possible to auto hide the panel? To be able to set it where I needed to drag it up from the bottom edge would awesome.
