Shift key for input fields disabled

Game is Steam version

Running on Steam-Proton (Linux Zorin-OS 17.2)

Tested on: Full game (80GB) and character creator demo (20GB)

EA-Help Case number 196990039

Problem: The SHIFT key is disabled for ALL input fields. No left shift, no right shift, no shift-lock is working. Keys with shift appear lowercase like it was never pressed.

Result: Not possible to EA login with a password that contains uppercase keys. Not possible to reset password, as this requires uppercase keys. Your char is denied to have a uppercase name. Savegames cannot have uppercase letters.

• Is shift generally switched off? Nope, movement for the char has working shift functions. This differs between input fields and gameplay.

Every idea is welcome, this is the only steam-proton game without shift key.
