This is a place holder, when using RDP smart sizing, on some systems, the font from the scaled RDP session may get blurry after a while.
Most searches advice to disable Anti-aliasing (3d), however there are many systems where this option is not available and if it is, it is a system wide setting.

The following reg change solves the RDP issue for the current profile (not system wide):
====================
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Avalon.Graphics]
"DisableHWAcceleration"=dword:00000001
====================

The reason to do this in one profile and not system wide has to do with Teams which can successfully use Hardware Acceleration (as of dec 2021), in this situation you can load Teams in a different profile and benefit from GPU offloading and not having blurry scaled RDP session(s).

Of course you can flip the profile use case around in which case you need to load the Reg changes in the other profile.

Run a program from a different profile in your own, Shift+Right Mouse Click (mix the use of Hardware Acceleration):
