Terrible performance when having multiple windows

Hi,

I’ve recently started using UE4 on my laptop due to a major move and I’ve been experiencing very bad performance in the editor when any window is “torn off” from the main window as well as the shader editor and object editor, the issue also occur with any right-click drop down menu and the autosave/undo message as well.

I have 2 monitors hooked into the laptop which it supports with MSI matrix display, one HDMI and one HDMI to mini Displayport connection.

I’ve tried installing latest drives for both Nvidia and the Intels graphics adapter which acts as the actual screen output.

The hardware is a Geforce GTX 960M

Any ideas on what could be casing it? Everything is running fine at 60fps when all the windows are docked or closed but when any window is appearing outside of the main one its running at 200+ ms
