It might be the same bug, but I'm not sure. It is strange, that it only affects systems made from Lubuntu Xenial Alternate, not from Lubuntu Xenial desktop.
So I created the bug report
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1572640
Maybe it will be considered a duplicate, maybe not.
