  Refresh change colours

Status in xorg package in Ubuntu:

Bug description:
  I had experienced few times that refreshing window causes some places to lose right information about colour. I mean that colours change to different for e.g. grey become yellowish, and strips are visible. Also in web browser some letters disappear.
  It is happening not often, maybe about 2/3 times per month. I am using Ubuntu 14.04, with following Hardware:
  Intel core I5 540M 2.53 GHz x 2 with Intel Ironlake Mobile graphics. System Is 64 bit version. 3,7GiB Ram.
  I'm using two screens with different size. First one is built-in laptop screen with resolution 1366x768 (16:9) and second one is Hitachi 22HXJ06U with resolution 1920x1080 (16:9). This happened to me also in Ubuntu 15.04, and before on Ubuntu 14.10. (In all cases the same hardware and two screens). Until now I notice this bug only when on firefox so I thought it could be something wrong with firefox, but today I noticed this bug on Terminal Window. I cannot really provide information how to create this bug - twice it happened on facebook when board automatically refreshed, and today it happened on Terminal when I clicked on firefox. I tried to repeat the problem with terminal, using the same commands but without positive results. Bug is fixing when window / application getting refreshed - scrolling up / down or moving window on screen fixing it. Creating Screenshot doesn't fixing it (done by default Print Screen with animation that everything becoming white and going to normal image)
  I also checked logs (/var/log/Xorg.0.log) but I dont see any error message or something - log finishing after screen setting up.
  I attached picture with example in firefox window (screenshots was bit edited - facebook's board, chat and chat list been deleted).
