I tried with another mouse and it works as expected. only connect the mouse no keyboard or display), it does not work. Even by unplugging everything else from the hub (i.e. It doesn't even matter if there is another external monitor connected. I have found out now, that the issue occurs only when the mouse (Logitech G402) is plugged-in. UPDATE 2 (): I am using a USB-C hub through which I connect my mouse, keyboard and display. So it seems to be related to the actual monitor somehow? I have tested it with a Sony 4K TV now (actually with an AVR that is connected to the TV) and it works fine. UPDATE 1 (): I use an external LG 4K monitor. Also, connecting to my company's network via RDP on a Windows PC works as expected. However, I can connect to a local Windows PC just fine even with an external display (no RDP gateway in-between).ģrd-party clients like Jump Desktop or Royal TS do not cause such problems. I also tried Microsoft Remote Desktop Beta (10.6.2, 1874) without success. So it works correctly only if just the integrated display is used. Disconnecting the external display renders RDP fine again. I have the same problem 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.
