Excessive GPU usage in Play mode despite limiting FPS via scripts

--

-

How to reproduce:
1. Open the user's attached "RefreshBug" project
2. Enter Play mode
3. Open Task Manager or any other system monitor
4. Observe Unity's GPU usage

Expected result: GPU usage is relatively low (0-25%)
Actual result: GPU usage is very high (35-60%) despite FPS being limited to the monitor's refresh rate

Reproducible with: 2021.2.0a2, 2021.3.2f1, 2022.1.0f1, 2022.2.0a13
Not reproducible with: 2019.4.39f1, 2020.3.34f1, 2021.2.0a1

Note: During testing, NVidia Geforce GTX 1650 Ti produced 20% GPU usage before the regression and 50% after the regression
