Why is my screen flickering?
Not everyone was reporting these problems, but there are certainly enough people experiencing this for it to get mentioned.
Flickering screen seems to be appearing on retina and non-retina screens, with Mac users noting that it can effect them when using Terminal, or when graphics are enabled or disabled. In some cases, it’s so bad that it makes looking at the screen impossible.

Subsequent macOS updates may have solved this problem, although a workaround or troubleshooting fix is often necessary even then. App pixel art mac backgrounds. Let’s look at how to solve it and get Mac screens working smoothly without flickering.
How to fix Mac screen flickering?
There are a number of potential solutions to this problem. It is worth trying each one in turn, then seeing whether the screen flickering issue is still present, or if one of the fixes has solved it; as each Mac may have a difference reaction to this hardware and software interactivity challenge.
1. Restart your Mac
Go to the Apple Menu > Restart.
Or Shut Down, then give it a few minutes before starting it up again.
2. Update your macOS
Go to the Mac App Store or Apple Menu > System Preferences.
If a macOS update is available - which means you aren't running the latest version (which could contain the automatic updates needed to solve this problem) - then a new macOS will be waiting for you to download it.
Back up your data beforehand, either to an external hard drive, third-party cloud-storage or iCloud.
Now follow the steps to update the macOS and once your Mac restarts, see whether the screen flickering issue is still present under the same conditions as before.
Assuming neither of the above solutions have solved this, there are a few other things you can try.
