Extreme lag on Microsoft Remote Desktop Mac client

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.

Hi @ElmarJense-5489

Does this happen recently (before it work without any lag)? No new changes or configurations made?
Do you have other monitor? Could this be related with the resolution of this 4K monitor?

We would also suggest to try the Microsoft Remote Desktop Beta, which is more stable.

Best Regards
Karlie

Just wanted to follow up, if a soultion was found?

I'm expiriencing the same performance issues with a Cinema Display connected to a closed MacBook Pro (2016).

The problem only occurs with a RD Gateway Server 2019 but works fine with a RD Gateway Server 2012, so if anyone has any suggestions I'd be grateful.

I tried the beta version with no success

After disconnecting the display the connection works just fine.

Thanks in advance

EDIT: Please see UPDATE 2 below.

I have the same problem @KarlieWeng-MSFT.

When I try to connect via RDP to my company's network (using an RDP gateway), it becomes unusable as soon as I connect an external display to a brand-new MacBook Air. Disconnecting the external display renders RDP fine again. So it works correctly only if just the integrated display is used. I also tried Microsoft Remote Desktop Beta (10.6.2, 1874) without success.

However, I can connect to a local Windows PC just fine even with an external display (no RDP gateway in-between).

3rd-party clients like Jump Desktop or Royal TS do not cause such problems. Also, connecting to my company's network via RDP on a Windows PC works as expected.

UPDATE 1 (2020-04-19): I use an external LG 4K monitor. I have tested it with a Sony 4K TV now (actually with an AVR that is connected to the TV) and it works fine. So it seems to be related to the actual monitor somehow?

UPDATE 2 (2020-04-20): I am using a USB-C hub through which I connect my mouse, keyboard and display. I have found out now, that the issue occurs only when the mouse (Logitech G402) is plugged-in. It doesn't even matter if there is another external monitor connected. Even by unplugging everything else from the hub (i.e. only connect the mouse; no keyboard or display), it does not work. I tried with another mouse and it works as expected. Is it possible that the RD gateway somehow dislikes the mouse? Or the polling rate or something like that? I also tried to connect the mouse directly to the USB-C port with another adapter, and it does not work correctly in RDP. So it's not the hub's fault.

@ElmarJense-5489 @MichelT-9450 Do you use a similar setup? Maybe this helps.

@CptLeergut-6116 great finding! I have a similar setup. cinema display with a usb hub in the back at which a logitech g502 and a apple keyboard is connected.
as soon as I disconnect the mouse and switch to a magic mouse the performance is normal good.

@KarlieWeng-MSFT is this a known issue?
