Has mouse layer on an external 4K screen. Details in the post. : mac



I use a late 13-inch MacBook Pro on the latest version of Catalina. It is connected to a 4K dell monitor using DisplayPort. The mouse is a Logitech wireless mouse connected to a USB dongle.

As the title says, I get mouse teams. It only happens on the external screen – not on the built-in laptop screen. It’s not the 30Hz delay some people get with external 4k monitors – I use DisplayPort, not HDMI, and get 60 Hz.

In particular, this started happening after I installed a Windows 10 bootcamp partition.

All help is appreciated!
