Issues with Ubuntu 16.04.2 with kernel 4.8

Hello,

I'm also running Ubuntu 16.04.2 with the 4.8 kernel and I'm experiencing massive slowdown as well. I tried to upgrade the driver to the version 1.3.52, but it made no observable difference. Chrome is really unusable, even gedit is super slow.

I believe I was on 4.8 kernel even before and it worked fine. The slowdown happened when I enabled the full Ubuntu HWE stack and Xorg got upgraded to a newer version.

glxgears reports 1 FPS when I move the window to a display connected via DisplayLink. Unfortunatekly I don't know FPS before the HWE upgrade.
