OSK is unexpectedly shown on the lockscreen
From mobians bugtracker (https://gitlab.com/mobian1/issues/-/issues/334#note_619867857)
Credit to @sotpapad for finding it:
- Click the "Search apps..." bar.
- BUG 1 - Keyboard is on focus and you cannot get rid of it unless you select an app.
- Instead of selecting an app, just push the power button so that the screen locks.
- BUG 2 - Push the power button again; the bottom of the lockscreen (including "0", "backspace", and "Unlock" after the upward gesture) is hidden by the virtual keyboard - which again you cannot get rid of.
I don't think BUG 2 is really its own bug, but rather a consequence of BUG 1
