DisplayLink shrinks App windows
 

When I launch the DisplayLink Manager, I have two problems.

First, all of the windows are gathered in my laptop window. This doesn't happen in my home setup, which also uses an external display, but not DisplayLink. The only workaround is to turn mirroring on and off. Not very inconvenient, but at least surmountable.

The second one is worse. All of my open windows have shrunk to an extremely short height. Some are little more than a thin line that's barely visible.

Has anyone else seen this, and if so, how do you get around it?
