Possible cause: We might not get keyboard layout changed events when we don't have focus (note repro requires removing focus in that step). Obviously, we shouldn't draw invisible text :) This would be in the TextBox code, so will require WinUI3, not possible in WinUI2.

Hi @Mogikan , we tried this on winui3 and it does not repro. Does this repro for you in WinUI3 ?
