[macOS] Editor has very low frame rate in a new project



Reproduction steps:
1. Create a new project
2. Try moving around in Scene view or check Editor frame rate in the profiler

Unexpected behavior: Editor has a very low frame rate (profiler indicates +100ms between frames)

Reproducible with: 2020.2.0a16, 2020.2.0a18
Not reproducible with: 20218.4.25f1, 2019.4.4f1, 2020.1.0b17, 2020.2.0a1a15

Reproduced with:
iMac Quad-Core Intel Core i5 3,4 GHz 32 GB ; Radeon Pro 570 4 GB ; Mac OS X 10.15.5 19F101 Darwin 19.5.0 up to 250ms between frames
MacBook Pro Quad-Core Intel Core i7 2,5 GHz ; 16GB ; Radeon R9 M370X 2 GB ; Mac OS X 10.15.5 ~100ms between frames
Not Reproduced with:
Windows 10 Intel(R) Xeon(R) W-2145 CPU @ 3.70GHz GTX 1080
macOS 10.14.6; CPU 2,5 GHz Intel Core i7; GPU AMD Radeon R9 M370X 2 GB; Intel Iris Pro 1536 MB

1. I was not able to understand what change happened between these 2 versions looking at profiler (the percentages of the functions were relatively the same)
2. Entering and exiting Play Mode resolves the issue
3. Changing graphics API to OpenGL 4.1 (on Mac) does not resolve the issue.
4. A video is attached

  1. Resolution Note (fix version 2020.2):

    Fixed by not having scene and game window show at the same time. When I have only the game window open I get 250fps but having the game and scene window open side by side gives me 80fps

    I'm facing these performance issues with any version (tried several 2018, 2019, 2020 and even the 2021 ones) on macos Big Sur and even the latest macOS Monterey beta.
    On the same hardware with windows none of the above can be reproduced, works flawless!

    I hope this is really fixed. I also have this problem in Linux.
