Here's what I've been doing as a workaround (although not perfect, see below):
Using normal SP3 settings connect using Remote Desktop Connection Manager (RDCM);
Add a server (the remote machine);
Under the server properties, Remote Desktop Settings tab, uncheck inherit from parent and select Full screen.
Under display settings, uncheck Inherit from parent.
After connecting, it may be necessary to sign out of remote and then reconnect using RDCM.
At that point my display appears normal.
However, modern/metro apps on the remote won't work when connecting with RDCM.
