Currently running the latest utopic kernel 3.16 and installed the Trusty Enablement Stack with sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic
It's having some pretty bad graphical rendering issues, like text is missing and my dialogue boxes are disappearing. (Screenshot attached). I tested this on a Lenovo X1 Gen 3 and a Lenovo X250, both of which can reproduce this issue. I also have a Dell M3800 which is not seeing this issue.
