I think they changed something. When I open RDP, the windows task bar is not cut off anymore, but it doesn't start at the bottom of the screen. Now the black bar from the screenshot of my first post is at the bottom. So I can see the task bar now completely but there is something cut off at the top of the screen (you can see it at the icons in the attached screenshot). The problem here is: When you have a maximized window, you cannot access minimize/maximize/close anymore.
Please see also that the RDP Controlbar at the top of the screen is doubled.
There is no solution for this Parallels-Bug as far as I know.
