What's your client?

MS MacOS client

Area(s) with issue?

Keyboard / Mouse

Steps to reproduce

When the MacOS client disconnects the keyboard is sometimes left in a state with a pressed Shift or Ctrl button.

When the same client re-connects - clicking on the menu items, for example, causes strange effects, because some special button is already pressed.

✔️ Expected Behavior

xrdp should restore all keyboard buttons to unpressed condition when the client disconnects.

It is extremely unlikely that another user would be working on the same keyboard and xrdp would mess up the keyboard's state.

❌ Actual Behavior

see above

Anything else?

I have to use the Florence virtual keyboard to un-press buttons, but this isn't easy.
