The on-screen keyboard fails to display the Input Method Editor (IME) when a key is pressed. Input is instead forwarded directly to the Steam client. This issue occurs for all keyboard layout which require an IME.

3. Connect a Gamepad.
4. Select a text field.
5. Press the Show Keyboard shortcut (Steam / Xbox + X or PS + Square or Home + Y).

_Note: If the ibus package is missing a Steam Deck specific error message will be shown. See https://github.com/ValveSoftware/steam-for-linux/issues/12221._
