How to reproduce:
1. Open the “ReproProjectPerf.zip“ project
2. Open the “SampleScene“
3. Enable the Development Build and Autoconnect Profiler in the Build Profiles window
4. Build and Run for Android
5. Connect the Profiler
6. Rotate the device to Portrait and back to Landscape several times
7. Observe the CPU Module in the Profiler

Expected result: The framerate does not drop to ~30 FPS for a bit when rotating the phone between portrait and landscape
Actual result: The framerate drops to ~30 FPS for a bit when rotating the phone between portrait and landscape
