From time to time I am seeing blue artifacts around black text and other pixels, this is happening on the internal and the external display, putting into sleep and waking or just moving the interface around seems to clear it for a while.
Is there a setting that will sort this out?

Hi TailsDog,
Thank you for reaching out to Apple Support Communities.
I see that you have an issue with blue color around fonts on your monitor. Restarting seems to fix the issue for a bit. I want to help. You can try a couple of resets. Neither will affect your data.
You can reset the SMC. Here’s How to reset the SMC of your Mac - Apple Support
If that doesn’t help, let’s reset the NVRAM. Here’s how to Reset NVRAM or PRAM on your Mac - Apple Support
I hope that helps!
Best Wishes!
Hi TailsDog,
Thank you for reaching back out to Apple Support Communities.
You can test to see if the issue happens inside safe mode. Here are a few quick notes about safe mode:
- Safe mode often looks and responds a bit different than what you're used to.
- Safe mode does not load everything that normally loads during a regular startup.
- Safe mode is a bit slower while loading and during normal operation as well.
- These differences can be cleared-up by a normal restart.
Here's how to boot into safe mode and Use safe mode to isolate issues with your Mac - Apple Support
Does the issue happen in safe mode? If not, restart again and try in typical mode. Just booting into safe mode in and of itself can resolve some issues.
I hope that helps.

Have attached a video showing this issue when switching between GPUs, this is on the internal monitor. It seems to happen with dark and light contrasting colors. The color profile is the default 'Color LCD'
Here is the screenshot that I was using in that video:
OK I found out that when night shift is active after sunset if the discrete GPU is active it will cause this issue.
Work around is to either enable graphic switching and disconnect the external monitor or deactivate night shift.
Hi Joseph
Thanks for your message, I've tried reseting both and still the issue is present.
What I am noticing is that it only seems to occur when the discrete GPU is active, I will try to take a video to show what is happening.
