I discovered this bug when I was running Compiz Fusion. This fix is only for Intel Atom N570 with Intel GMA X3150 video card, running on Debian Jessie (8.4) and MATE Desktop (1.8.1).

¿What's the problem?

If you check /var/log/Xorg.0.log you have this message:

intel(0): Failed to submit batch buffer, expect rendering corruption:
Resource deadlock avoided.

¿How to fix?

Very easy. We need update xserver-xorg-video-intel (2:2.21.15-2) to xserver-xorg-video-intel (2:2.99.917-2~bpo8+1) package from Debian Jessie backports.

Steps:

1.- Open a terminal and type.

$ cd /
$ sudo pluma /etc/apt/sources.list

2.- Add the lines:

deb http://ftp.debian.org/debian jessie-backports main contrib non-free
deb-src http://ftp.debian.org/debian jessie-backports main contrib non-free

3.- Save and exit.

4.- In that terminal, type:

$ sudo apt-get update
$ sudo apt-get -t jessie-backports install xserver-xorg-video-intel
$ sudo reboot

That's all.
