I can confirm that there is an improvement with 3.16.0-37-generic on a
X1 Carbon 3rd gen. For example the shutdown menu and all the other
dropdowns in the black menu bar are fixed for me. It still appears in
3rd party apps, such as Guake or Libre Office (those two are
particularly annoying as you can guess).

Bug description:
Trying to achieve: Get a more stable graphics environment up and
running
Steps to take: basic ubtuntu 14.04 install. Boot up and run for a
few minutes and then ...
What happens: After running for a few minutes the graphics gets
flacky.
What should happen: Graphics should not get flaky.
I have just installed ubuntu 14.04 on my new thinkpad t450s.
Everything basically works, but something is very flaky about my
keyboard or display or both. After running for awhile some apps
(E.g., thunderbird and sometimes emacs for example) will display
garbage. If I refresh by moving the screen around or changing
buffers/tabs/etc. they can often recover.
I see that there is an [Intel(R) Graphics Installer for Linux*
1.0.7](https://01.org/linuxgraphics/downloads/2014/intelr-graphics-
installer-linux-1.0.7). I am leery about just loading this and running
it. Any suggestions about how I should proceed?
