This options worked for me:

Option 1# The Problem ist related to the Mouse Pointer Shadow Function.

Within RDP this leads to a hopping/slow mouse.

Correct this behavior with Mouse -> Pointer -> Enable pointer shadow (disable)

Option 2# DisableTaskOffload 

Open RegEdit on the Windows Server machine. Navigate to this registry key in the tree on the left: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

  • Right-click on the right side, and add a new DWORD (32-bit) Value Set the value name to DisableTaskOffload and the value data to 1
  • Reconnect to the Server via RDP (to a new session) and your performance should be normal.

Option 3# Disable service Smart Card Device Enumeration:

  • Go to Run –> Services –> Smart Card Device Enumeration –> Disable
