I would install the fix from microsoft what @garlin said.
Disabling UDP might cause slowing down of refresh rate in RDP. as it is forced to use TCP.
TCP will establishes a connection between the sender and receiver before data is send, and has checkup if data is send correctly and if faulty it resends it again (causing the slowdown)
UDP is connectionless, it will send the data without establishing a connection, what does not gaurantee packet dilivery.
For picture output UDP is ok, as the next batch of info is send directly again, and so it will refresh again.
Especially over slower connections the resending of TCP data will make it a lot worse experiance.

However if it is a temparary fix for a few weeks it might be ok in some situations.
