I assume if it is happening in mirror mode, the jerky mouse is only seen on the DL screen and not both screens?

The problem exists only when using "second screen only" - with the lid closed! This is really strange because the laptop screen is turned off anyway. The difference is that when you close the lid, windows makes the "second screen" into the "pc screen".

Works perfectly - no lag:
When screen is extended or mirrored.

And it's not links on web pages, it's most graphics that is being drawn. Scrolling a window, elements on web pages changing color etc. BUT strangely enough some graphic changes does NOT create lag. For example the taskbar buttons, ribbon menu buttons or taskswitch thumbnails. It's like it's affected by graphics that is drawn "the old way".

The problem is also affected by network traffic. When something uses the ethernet everything lags. When downloading something everything basically comes to a stand still.

Basically it doesn't work when windows is using only one screen and that screen is the usb 3.0 dock.
