Title:
  lightdm crashes on window open in Ubuntu 15.10 intel

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  On Ubuntu 15.10 I get crashes, when I open a new window in an already
  started application. It happens irregularely, but I can force the
  crash if I open several new message windows in thunderbird. But it
  also happens in other applilcations, for example a new terminal
  window.

  This is the output during the crash in /var/log/Xorg.0.log
