I just saw [here](https://bugs.launchpad.net/ubuntu/+source/lyx/+bug/129813) that this might be related to more general NVIDIA related X issues, that are [supposedly solved in the latest X 1.19](https://devtalk.nvidia.com/default/topic/976844/xorg-1-19-support/). I am on a fresh test install of Ubuntu 17.04 using the 340.102 driver now ([which supports X 1.19](https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA- Legacy-6-Fermi-1.19))and confirm that lyx performance is good.
