Embedded RDP scaling issues on Windows 10

I have upgraded my laptop from Windows 8.1 to Windows 10 Home. After the 8.1 to 10 upgrade I performed a clean install of Windows 10 Home.

After the clean install of Windows 10 I installed RDM 11.0.18.0 Enterprise and found that embedded RDP sessions set to "Fit RDP window (smart sizing)" would no longer fit the 1280x1024 RDP session embedded in the RDM window on my 1920x1080 desktop. There is a blank section at the bottom of the embedded RDP session and that blank section must be clicked on to change to programs that are listed on the Task Bar.

I searched the forum before posting this and found information about RDP session issues on http://help.remotedesktopmanager.com/troubleshooting_rdp.htm which helped with my initial scaling issues (the embedded RDP session not only had the blank section at the bottom but was also improperly stretched within the RDM window). I have set my desktop scaling to 100% instead of 125% which has resolved the improperly stretched issue but it has not fixed the blank section at the bottom of the embedded RDP session.

The workstation I am connecting to is Windows 8.1 Enterprise.

I have attached a screen shot of the issue with the blank section outlined in red.
