4.16 Mobile Compat Pass - QA-Decals - UI glitch when playing on a 9.3.5 iOS Device

While testing in QA-Decals on iOS device, after loading into the project the UI will be glitched ~50% of the time.

After further testing, it seems this bug only occurs on iPads running the iOS version 9.3.5.

Repro Steps:

1. Install QAGame package from Root/Build/UE4/Manual_Build/MobileCompatBuilds/MobileCompat_3402086/QA-Decals onto an iOS device
2. Open the project on the device
3. *If loaded into map QAEntry* hold down four fingers on the device screen to open the Console and enter the Command Open QA-Decals

Result:
The UI surrounding the right joystick loads in distorted and pixelated
Expected Result:
The UI loads properly. Three circles, Green "Jump" - Red "Crouch" - Yellow "weapon"
Frequency:
3/6
