MacOS screen capture flickering (blinking)

Bug report

MacOS screen capture leds are constantly flickering. This happens both when capturing is set to the OSX and QT, no matter what kind of capture frequency is set. With higher frequency the issues is still there but less visible. I tried to eliminate it completely with smoothing, but it just won't go away. It's not terrible when frequency is set to 25fps or above, but it shouldn't be there at all. When you look at your led strip, when there are color transformations happening it looks not as smooth as it should be. Not terrible (with 25fps capture or above) but also not great.

Please look at this video illustrating the issue: https://cln.sh/Xz9QtPZc

Thanks!

Steps to reproduce

1. Install Hyperion for MacOS from the official release package.
2. Check the Live Video feed
3. There will be flickering happening in the preview window

What is expected?

No flickering, smooth screen capture.

What is actually happening?

You can see constant flickering of the captured picture, next to the led layout preview.
