Flashbulb graphics effect gets screen stuck completely black

 Release used
==============

Description: Ubuntu 16.04.3 LTS
Release: 16.04

 Package version used
======================

  Installed: 3.18.0-1ubuntu2
  Candidate: 3.18.0-1ubuntu2

 What was expected
===================

When taking a screenshot with GNOME Screenshot by pressing the PrtScr button, the screen will have a flashbulb graphics effect, where the screen gets bright white, then black, then back to normal.

 What happened instead
=======================

The flashbulb graphics effect went to black and stopped there, leaving the GUI unusable and forcing me to reboot to get things back to normal.

This didn't happen before my upgrade today from a 4.10 kernel to a 4.13 kernel (specifically 4.13.0-26.29~16.04.2), so that may be related.
