[Android] S20 freezes with Swappy enabled when Vsync is being manipulated at runtime

Mobile

-

Steps to reproduce:
1. Open attached "BoatAttack" project
2. Make sure "Optimized Frame Pacing" is enabled under Player settings in "Resolution and Presentation"
3. Make sure that under "FrameDisplay > Text" game object, "Frame Show" script, "Enable Scenarios" bool is enabled
4. Make sure device is set to Refresh rate of 120Hz
5. Run "demo_island" scene on device
6. Leave it running for a while (1-5 minutes should do it)
7. After some cycles of the Vsync scenarios loop over eventually the app will just freeze (Music is still playing, but new frames aren't rendered)
(Device log attached)

Expected: App should not freeze
Actual: Seems like 120Hz Refresh rate and Vsync manipulation is causing the app to freeze sometimes

Reproduced with: 2020.1.0b12
