The UI Blur looks awesome, so I’ve redesigned some of my menus to use it.  
In mobile preview, it works and looks great, but on my device (Nexus 6P) it uses the low quality override.  
Is this a problem with device profiling? I actually have the same problem with custom depth stencil. Works in preview, but not on my test device.

Thanks!

UPDATE: It doesn’t even use the low quality override for me, it just goes straight black.

I`m suffering the same problem as well. The UI blur just goes straight black on mobile.

Hi, I have found there is already a bug report about this problem: [Unreal Engine Issues and Bug Tracker (UE-39515)](https://issues.unrealengine.com/issue/UE-39515)

Thanks for the update! I noticed the bug said Nexus 6P. Is that the device you’re having issues with also?
