Regression between 4.8.1 and 4.7.4

How to reproduce:

  1. Create first person template Open
  2. FirstPersonHUD (canvas blueprint)
  3. Replace draw texture node with
  4. DrawMaterialSimple node Use attached material in that node
  5. Hit ensure slowing down startup playback looking like this:

Hi dgrieshofer -

Thank you for your post. We had a report of this ensure but were not able to get a successful simple reproduction. It looks like it is the Responsive AA that is causing the ensures. I have added your reproduction and information to the bug report, for reference UE-17723. As we investigate a solution I will keep you informed here.

Thank You -

Eric Ketchum
