Problem
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.
Cause
Start Thunderbird,
“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,
start typing.
Either no output appears, or suggestions are highlighted on OSK.
It looks like every key-touch is immediately backspaced.
Related Issues
Once issue is triggered, other applications are potentially affected (launched Firefox and Chromium and saw same behaviour)
Workarounds
Reboot (or change tablet orientation to rotate screen once)
