You do not have enough vertical screen space to have the mixer and inspector docked and stacked on top of one another and also be able to see the piano keyboard docked below. You might try restoring (un-maximizing) and re-maximizing your window. That seemed to help in my case. You can also undock the inspector or the mixer or the piano keyboard.

Thanks to Matt and Geet for your replies. I have further tested the bug with these results:
1. I verified that Piano View was being shoved off the bottom of the screen.
Comment: This did not used to happen two updates ago---the Mixer View on the right stayed vertically bounded in the program window.
So this is a new aberrant behavior of the last two updates, from my point of view. 😶
2. Once the Mixer has been Viewed, the Piano View can not be brought back on screen, even when turning off View Mixer.
Comment: The Mixer View iteself pushes off the bottom of the screen with improbably-elongated slider bars. [see Screen Shot]
In fact I cannot even resize the main program window vertically with Mixer View On and Piano View Off.
Comment: If I were a Dev I'd check the Mixer View Window code---it seems to have come undone at the bottom bound. 🤔
That said, I am not a dev. 😊
3. Expected behavior: "P" toggles piano keyboard on and off at bottom of screen regardless of what's stacked on the right. Views on the right, including Mixer, stay bounded within the program window---use scroll bars if needed to view.
