Scaling issue is caused by Remote Desktop Client lack of being DPI scaling aware. If you open a Remote Desktop connection to a server or other computer the native resolution of the computer is used instead of the scaling to 1920×1080, so you’ll get very small icons, fonts or lines would overlap etc.
Another solution where you don’t need extra tools or programs is to make a manifest file, see the steps below.
First tell Windows to look for a manifest file for an application by default. This can be done by setting a registry entry.
1. Open regedit and navigate to the registry key: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide Right-click, select NEW -> DWORD (32 bit) Value Type PreferExternalManifest and then press ENTER. Right-click PreferExternalManifest, and then click Modify. Enter Value Data 1 and select Decimal. Click OK. Exit Registry Editor.
2. Next step is to make the manifest file, mstsc.exe.manifest. Copy the contents below and put it in Notepad or similar tool and Save it as file named mstsc.exe.manifest and Save as type : All files. in following location, %SystemRoot%\System32\

This is also solving the same issue for applications published through RemoteApp and Desktop Service
