Steps to reproduce:
1. Open the attached user's project "URPRepro.zip"
2. Open "Assets/Materials/Background.shadergraph"
3. Make sure that the Dither Node is connected to the output
4. Make sure Development build and Auto Connect Profiler is enabled
5. Build to a Samsung Galaxy J7
6. Observe the Profiler or using 3 fingers tap on the screen to open the display stats UI and observe the reported average FPS

Expected results: Enabling a Dither Node in a ShaderGraph does not cause Semaphore.WaitForSignal to take up 200ms
Actual results: Semaphore.WaitForSignal causes ~200ms stalls when Dither Node in a ShaderGraph is enabled on Samsung J7

Notes:
-According to the user "Application.targetFrameRate is set to 300 on a 60 hz device, but the issue happens if we don't set targetFrameRate"
-Issue reproduces with Vulkan and OpenGLES 3
-The slowdown (Semaphore.WaitForSignal) is caused by the Dithering Node used in the "Assets/Materials/Background.shadergraph" Shader Graph
-Profiler data of the affected devices is attached ("SamsungJ7_6000_0_20f1.data")
-Profiler data of the affected user device is attached ("Galaxy A32.data")
