just try latest vivid distro kernel from proposed, which switches
Broadwell to use i915_bpo module (backported from 4.2)

you're probably seeing a GPU hang which is known to happen with 3.19 and
one of the reasons for the switch, dmesg should confirm that.

Title:
  Faulty graphics behaviour when resuming from suspend with intel
  graphics drivers

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Waking from suspend, everything seems normal, except the graphical
  elements and text on my desktop are not drawn properly. Sometimes,
  moving the mouse over icons can cause them to be redrawn, sometimes
  not. It appears not to matter how I initiate the suspend (e.g. by
  closing laptop lid, or by calling pm-suspend explicitly) and it
  appears not to matter whether I am using an external display or the
  laptop's own screen. All other hardware appears to be working, and I
  can restart the laptop by clicking where the icons ought to be. The
  only symptom seems to be that the drawing does not happen correctly.
