Xorg.0.log
This issue came up after upgrading to the latest version of the intel driver.
My terminal emulator has very poor performance and some programs don't show
text.
General system performance is way worse than before.
Using version: 1:2.99.917+364+gb24e758-1, Thinkpad X1 Carbon, Intel Core i7
3667U with an Intel HD Graphics 4000
Downgrading to 2.99.917-5 fixed the issue.
