I experience similar problem but with Intel graphic card i915. And mostly when using Google Chrome, LibreOffice or Viber. For example, I clicked Tools -> Options in LibreOffice and I was returned to login screen. Or I was zooming google maps... or when talking to someone on Viber... I believe it has to do something with hardware accelerator or openGL? (I am just an ordinary user so do not take my comments so seriously). I noticed that LibreOffice does not allow to enable Hardware Accelerator from time to time...
When Ubuntu 15.10 was published, this was happening more often. Now, it happenes rarely.
