I am using a Lenovo IdeaPad U430p with Ubutu 14.04 LTS. There is a GeForce GT 730M built in and there are also some drivers available:
NVIDIA binary driver - version 331.38 from nvidia-331 (proprietary, tested) NVIDIA binary driver - version 331.38 from nvidia-331-updates (proprietary) X.Org X server - Nouveau display driver from xserver-xorg-video-nouveau (open source)
Whichever driver I use, video in chrome are flickering on fast movement. It seems that the screen is cut in half for a few milliseconds. I tried enable/display Override software rendering list at chrome://flags/ but it changes nothing.
