Remote desktop connection from windows 10 to a terminal server windows 2003 graphics garbled

I have a few users who connect to a server 2003 terminal server and the ones who are using windows 7 can connect fine with no issue like they have for years. Now windows 10 users with the same settings are getting garbled graphics and screens that are difficult to read. I've also tried the remote desktop preview app to connect to the 2003 server, but there's obviously a compatibility issue because the screen is just blank.

Has anybody heard of this issue, and are there any clues you can give me on how to fix this?

Can you match the video resolution of the Windows 10 machine with the video resolution of Server 2003. I use RDP with Windows 10 to Server 2012 and 2008 and that works. All the old Server 2003 machines are gone.

I found the answer, I had the color depth set at max 8 bit in the global policy for the org unit the terminal server was in for performance, and apparently windows 10 rdp doesn't support that. As soon as I changed it to 16 bit, the sessions were clear again.

If your older terminal servers are set a lower color depth than 16 bit, the graphics will be garbled when you connect to it from the windows 10 rdp client.  Changing the the default color depth to at least 16 bit will solve the problem.
