I experience extreme lag in all my actions on the MacOS Remote Desktop Client, where every mouse click takes up to 30 seconds to take effect.
my setup is the following;
MacBook Pro 15" (2015)
External USB-C 4K monitor (lg)
This problem only occurs when the external monitor is connected. If I only use my Macbook, there is no lag at all.

Same issues here!
Config:
Seems to occur when I plug my monitor HP 24f into the HDMI port. Even directly in the laptop!

I'm seeing the same issue on a brand new Mac Mini M1.
The only things conncted is: Samsung 4k monitor U32J590U via HDMI, MS Surface keyboard wireless and Razer Deathadder V2 Pro via 2.4GHz.
I have tried both normal and beta RDP client, connecting to RemoteApp.

Also same issue on mac mini. RDP 8 worked great, until Big Sur, then it started crashing on startup.
V10 and the beta are both so delayed as to be very frustrating to use. Tried plugging mouse directly into , mac mini (avoid the usb hub), made no difference.

I faced to exact same problems.
I using my MacBook connected to an external 4K display (Gigabyte M32U) via a single Thunderbolt 3 cable.
Mouse and keyboard are both connected to the hub in the monitor.
I'm also connected via RDP Gateway.
Microsoft Remote Desktop is so laggy, it's completely unusable. I don't have this problem with any other application, it's only in RDP.
When using the built-in trackpad and MacBook keyboard everything is ok (not as fast and fluid as on Windows, but it's usable).
@Karlie Weng it‘s really sad to see this issue still exists, a year after it was first reported. And there is no comment or statement by MS on this topic.
The community narrowed it down to a very specific problem. Could you reproduce it (at least)?

I'm running an older Intel-based Mac Pro, and I can confirm the same issue. For me, I'm watching a video in Microsoft Stream to ensure a constant feed of data over the wifi connection, and it seems the wifi connection is the issue:
Compare that with the network connection on my Mac:

Changing the polling rate from my Logitech Pro Wireless mouse to 125 Hz in the G Hub Software solved the problem at least in my case. When I turned it back on to 1000 Hz the lag started again.
It doesn't work with my G Pro X Superlight. However, that's a bug in the Logitech software. It doesn't accept changing polling rate...
However, I don't think it's an acceptable solution to set your mouse back to year 1995 ... all modern mice use 500 or 1000hz ...
These polling rates work flawlessly on the Windows version of Remote Desktop (same gateway, same target host) but they cause complete chaos with the macOS version.
That's a bug in the macOS RDP client and nothing else ... It's a shame that Microsoft doesn't respond in any useful way to this issue.

Disabling hardware improves the performance. Its not that fast but its usable. Thanks for the tip.

Thanks for the many good hints here. Another thing to look at is the polling rate of the mouse. If you have a professional/gaming mouse, the polling rate can normally be adjusted. Bringing it down from 1000 to 150 or 200 Hz did solve this issue for us. This is why it helps to disconnect the mouse sometimes.
