ThinOS 9.1.3112 slow direct RDP connection

Hello Community,

I hope you can help me.
Two days ago we updated a few ThinClients with the Wyse Management Suite from ThinOS 8.6 to the latest ThinOS 9.1.3112.
Of course we also updated the Microsoft App to version wvd 1.2.1157.

The ThinClients have to connect to the server with a direct RDP connection, which works so far.

However, since the update to ThinOS 9.1, there is the problem that every RDP connection is permanently laggy and sometimes causes a time delay of up to 2 seconds.

UDP and TCP on the RDP server is active, UDP connection is also possible.

I hope you can help me in this case, so that I can satisfy my customers.

What else I noticed, it needs until he gets an IP address, since ThinOS 9.1 relatively long 20-30 seconds.
Of course, a ThinClient has already been reset to factory settings.
