Reproduction steps:
1. Open the user’s attached “Camera.zip“ project
2. Build and Run for Android with “Development Build“ and “Autoconnect Profiler“ boxes checked
3. In the Profiler Window search for “UnitySynchronizationContext.ExecuteTasks“
4. Observe the “Time ms“ table
Expected result: Duration for “UnitySynchronizationContext.ExecuteTasks” calls is ~0.01 ms
Actual result: Duration for “UnitySynchronizationContext.ExecuteTasks” calls is ~0.1 ms
Reproducible with: 2020.3.40f1, 2021.3.12f1, 2022.1.20f1, 2022.2.0b11, 2023.1.0a13
Reproducible with these devices:
Samsung Galaxy Z Flip3 5G (SM-F711B), Android 12, CPU: Snapdragon 888, GPU: Adreno (TM) 660
Samsung Galaxy S22 (SM-S901B), Android 12, CPU: Exynos 2200, GPU: Ltd.
Samsung Galaxy S10+ (SM-G975F), Android 10, CPU: NOT FOUND, GPU: Mali-G76
Couldn’t test with these devices (Can’t test with Mono Scripting Backend on iOS devices and thus check the difference with IL2CPP):
VLNQA00358 - iPhone 12, 14.1 iOS
VLNQA00310 - iPad Pro 12.9", 13.4.1 iOS
VLNQA00392 - iPad (9th generation), 15.0 iOS
Not reproducible with: Windows Standalone
Tested with: Windows 10
Notes:
- The difference is seen the most in 2020.3.40f1
- The difference is starting to get smaller in 2022.2.0b11, since call time in Mono is ~0.03 and in IL2CPP is ~0.06
- The issue seems reproducible with VLNQA00358 - iPhone 12, 14.1 iOS device, but it’s not possible to check with Mono Scripting Backend
