Title:
  Scrambled UI: Text in the Unity windows disappears/mixed after the
  resume from the screen idle state

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Text in Unity windows becomes a total mess after suspending and waking up 
Ubuntu 16.04. Text content in most of system and native windows are scrambled 
including terminal, nautilus, native apps EXCEPT Java apps (browsers and Libre 
Office work fine).
  I had this issue multiple times, but it is not always reproducable.

  This bug occurred now in linux-image-generic 4.4.0.53. Earlier it
  occurred multiple times on linux-image-extra-4.4.0-47-generic
  4.4.0-47.68 amd64 Linux kernel and some earlier versions (see
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1641152). It did
  not appeare on linux-image-extra-4.4.0-51-generic 4.4.0-51.72 amd64
  and now it appeares again (on linux-image-generic 4.4.0.53).

  I was not able to report it via the apport-collect. The console window was 
totally ureadable, but the recovered output is:
  $ apport-collect 1641152
