Steps to reproduce the problem:
1. Click on the time area in the bottom right to open the menu.
2. Click on the icon next to the volume slider to open the input/output audio video settings
3. CLOSE the window out
4. Go back and repeat the process again -- the second time you go back the input/output settings menu does not properly open.  You have to sign out or reboot machine

What is the expected behavior?
The input/output menu should open up every time the same

What went wrong?
The SECOND time you try to open the input/output menu, only one small white box appears with the header line "AUDIO".  It's like the menu is cutoff or hidden below the screen.
It seems to occur pretty consistently.  It happened on 3 different machines on a recent update in the last 2 weeks.

Did this work before? Yes Unknown -- issue only appeared in last few weeks.

The issue occurred at the same time as a 3rd USB based monitor bug appeared (in another report note).
