The on screen keyboard is stuck in “suggest a word” mode (lists words above keys), and does not type to screen. AFAIK only “Enter” and “backspace” are relayed.
Issue first discovered in Thunderbird on a Dell Tablet (WACOM Touchscreen).
Freshly installed F37 Workstation.
“write” new message,
tap the “message text area” → the on-screen-keyboard does not appear,
pull up OSK (gesture: swipe from bottom up),
focus on “message text area” lost → tap again,
Either no output appears, or suggestions are highlighted on OSK.
It looks like every key-touch is immediately backspaced.
Once issue is triggered, other applications are potentially affected (launched Firefox and Chromium and saw same behaviour)
Reboot (or change tablet orientation to rotate screen once)
