I have a Thinkpad X200. I installed Ubunntu 16.04.3. It works fine immediately after installation (kernel 4.10.0-28). But when I install updates (kernel 4.13, post Meltdown/Spectre), it starts to behave weirdly:
WHAT HAPPENS:
All Unity eye-candies stop to work and cause a session refresh. I mean, when I press Alt (HUD), or Super (Dash), or even when I hover my mouse over an icon on the launcher the system goes through a mini-crash: all elements on the screen disappear for ~2 seconds, and they come back again. I never see HUD, Dash, or the laucher tooltip that I intended to see.
POSSIBLE PROBLEM:
Is it safe to say 3D accleration has stopped working after kernel update?

I tested this on a non-Libreboot (i.e., stock Lenovo BIOS) ThinkPad X200s. Exactly the same problem.
