Having the same issue myself.
Xorg process gradually consumes more and more RAM over time until the
desktop becomes unusable and either crashes, or needs to be rebooted to
get going again.
== In my case below, PID 2012 is currently up to 2.1GB of RAM again.

Title:
Xorg memory leak on trusty
Status in “xserver-xorg-video-intel” package in Ubuntu:
Fix Released
Bug description:
After a few hours Xorg process was consuming a GB of RAM, after a day
or so it was 2GB, now after 2 days it's over 4GB. I'd rather X wasn't
eating all my RAM.
