Memory leak when unloading unused assets with Metal

iOS

-

-

Priority: 2Necessary for shipping a final release

-

Severity: 1Crash, freeze, data loss, work stops

Memory is continuously allocated (2 KB at a time) each time a scene is loaded on iOS with Metal as the Graphics API.

Steps to reproduce:
1) Open the attached project.
2) Build for iOS or as Mac standalone with Metal as the Graphics API.
3) Run on a Metal-capable device.
4) Using Instruments, monitor the memory allocations.

Memory is allocated (2 KB on iOS and 3KB on Mac standalone) each time a scene is switched. The memory buildup causes the app to crash eventually.

Reproduced on:
5.6.0a2, 5.4.3f1, 5.3.7p1

Devices:
MacBook Pro Early 2013
iPhone 7 iOS 10.2
iPad Air 2 iOS 8.1
