Scratch my last comment. I'll add some screenshots with the issue
(hovering the mouse on top of unrendered text shows it temporarily).

After that I'll try to bump my kernel, but will need some days of
testing to reproduce problem

Title:
  Suspend breaks on gnome session not on unity session - dell xps 14z

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I've got two users on this computer. When using gnome 3 session the
  suspend behaves really quirky. After suspend it might have rendering
  problems or it doesn't come back or it comes back with a very slow
  response afterwards.

  In Unity the problem doesn't appear, so a hardware problem seems to
  not affect this other software.

  I'll try to make a screenshot of the rendering problem
