The on screen keyboard is unusable on frieza_arm64/staging. It's just not displayed.

That last one suggests unity8 didn't properly pick the input method up.

Interesting it's always and only the OSK we have rendering trouble with (see also bug 1590765, bug 1649077). Might be worth looking into how the OSK renders differently to other apps.
