[Metal][HDRP]Editor activity spikes on Semaphore.WaitForSignal when Shader Graph window is open and undocked
How to reproduce:
1. Open the attached project ("HDRP_Performance")
2. Open the Profiler and enable the Profile Editor
3. In Profiler, select the Hierarchy preview
4. In Profiler search field type Semaphore.WaitForSignal and press record
5. In Assets, double click on the "TestShaderGraph" and make sure that Shader Graph window is undocked
6. Observe the Profiler
Expected result: Semaphore.WaitForSignal does not spike
Actual result: Random Semaphore.WaitForSignal spikes are visible
Reproducible with: 2019.1.9f1(HDRP 5.7.2, Shader Graph 5.7.2), 2019.2.0b7(HDRP 6.7.1, Shader Graph 6.5.2), 2019.3.0a9(HDRP 6.5.2, Shader Graph 6.5.2)
Not reproducible with: 2018.4.4f1(HDRP 4.1.0, Shader Graph 4.10.0), 2019.1.0b6(HDRP 5.2.3, Shader Graph 5.2.3)
Notes:
- On 2019.3.0a9, the issue is reproducible without any undocked windows
- Testing 2019.2.0a6 and earlier resulted in inconsistent reproduction, most likely due to the inconsistencies of HDRP compatibility

Resolution Note:
Please try to use the new Profiler Out Of Process (see profiler user preferences) and see if it helps and reduces the noise and lag of the profiler window itself while profiling.
