Comment 123 for bug 1386721

Hi there. I had the same problem (especially noticeable in Chrome) on Ubuntu 16.04 (latest updates) with Gnome Shell installed and using the Dell XPS 13 9350 (latest firmware updates installed) with two displays (4k & 1080p) connected via Displaylink Docking Station D3000.

The fix of philipp_023 fixed it! Thank you very much for sharing!
Using the notebooks UI felt laggy like hell but now things run incredibly smooth again :) There are still minor bugs or lags when I interact with the Gnome UI or change display settings but this comes very certainly from the DisplayLink driver I had to install.

Cheers!
