[MacOS] Performance regression when dragging nodes in ShaderGraph window on heavy GPU load/integrated GPUs

Package: Shader Graph

-

How to reproduce:
1. Open attached project "shadergraph_bug.zip"
2. In the Project window, go to Assets and double-click "graph"
3. Undock the ShaderGraph window and maximize it
4. Try dragging the "graph" or any other node

Expected result: there is no dragging delay
Actual result: there is dragging delay

Reproducible with: 6.9.0, 9.0.0-preivew.14 (2019.2.0b9, 2019.4.2f1, 2020.1.0b14, 2020.2.0a17)
Not reproducible with: 1.1.1-preview, 6.7.1 (2018.4.24f1, 2019.2.0b9)

Notes:
Reproduced on macOS Catalina 10.15.5 Intel Iris Pro 1536 MB with Metal and OpenGLCore APIs, reproduces with all ShaderGraph graphs
Didn't reproduce on a Windows 10 with Intel(R) UHD Graphics 630, tested with Direct3D11, Direct3D12, Vulkan, OpenGLCore, OpenGLES2

  1. Resolution Note:

    This behavior is unfortunately very difficult to mitigate in our current graph UI framework. We are working to replace that framework and ensuring the performance of the new framework does not have this issue.
