How to fix my MacBook pixels are acting weird

The text in the picture is not important. What is important is the colors in my MacBook that are partly in negative colors.

It could be important if the issue is software-related, and not a hardware issue.

Are you running any anti virus, Mac "Cleaner", Mac "Optimizer", or Mac "Speeder Upper" software? Often they create issues, and are not recommended at all. Use the software vendors' uninstaller to rid your Mac of these unneeded apps.

Does the same thing happen when you boot into Safe Mode? Start up your Mac in safe mode - Apple Support

when you post a Picture with a message in it instead of the TEXT of the message, non-native speakers of your language have no reasonable opportunity to auto translate the message.

If you copy and paste the TEXT, I can get a search engine to translate it for me.

Based on exactly what you posted, my only diagnosis is: "your Mac is putting up pictures of messages that are not in a language I understand'"
