Just for anyone who wants to turn DR3 back, here is the solution I
found:

- You need to have a DRI3 enabled xserver-xorg-video-intel driver. You
can get one from the xorg-edgers ppa. I just downloaded the deb file
that suits for my Ubuntu architecture from here: https://launchpad.net
/~xorg-
edgers/+archive/ubuntu/ppa/+packages?field.name_filter=&field.status_filter=published&field.series_filter=vivid

After that just do
sudo dpkg -i ./name_of_the_debfile

- xorg configuration needs adjustments. Just do
sudo vi /etc/X11/xorg.conf

and insert:

Section "Module"
        Load    "dri3"
EndSection

Section "Device"
  Identifier "Intel"
  Option "DRI" "3"
EndSection

Now everything runs much smoother, without a sign of tearing.

Title:
  Disable DRI3

Status in xserver-xorg-video-intel package in Ubuntu:
  Fix Released
Status in xserver-xorg-video-intel source package in Utopic:
  Fix Released
Status in xserver-xorg-video-intel source package in Vivid:
  Fix Released

Bug description:
  [Impact]
  from the upstream commit:

  "The external libraries, both in git, and especially shipping already
      enabled in distributions, are buggy and lead to server crashes and
      lockups. Caveat emptor."

  so disable it by default in vivid and utopic.

  [Test case]
  grep DRI3 /var/log/Xorg.0.log
  should not return anything

  [Regression potential]
  none
