Display problems with Linux Min V19 Cinammon

The display issues even caused my initial post to not have any body text (popup blocked text box) and you don't allow the author to edit their own post.

Keystroke forwarding (esp. alt-tab) to the remote sesssion doesn't work.  Now that I'm forced to constantly minimize and restore the Teamviewer window, that results in problems as well.  When minimizing, the title bar disappears and the remainder of the window is there and can't be reduced to the bar (known as the 'taskbar' in Windows).  If I try select an menu option from the Teamviewer window, nothing happens.  Occassionally, I'd see part of the context menu, pop up behind the foreground window, but no option to gain focus there.

This appears to be a Teamviewer problem, since I don't have that problem with any other application window.
