Developer Notes

This will now revert to low quality mode for android


Tested on Nexus 6P with Android 7.0


Suggest that on mobile the background is not rendered in real time, instead we render the blurred image for one frame and use that same image for subsequent frames as long as the blur widget is still onscreen.  So if the user brings up an overlay window which blurs the background, the background game scene will appear to pause.

Steps to Reproduce
  1. Create a UMG Widget that uses the blur component
  2. Add the widget to your viewport via the level BP
  3. Pie, observe that the blur works
  4. LaunchOn or package, install, and open it on an android device

Result: Observe that the area where the blur is in the UMG widget is rendered black

Expected: Parity with the editor and pie
