I am using Visual Studio Code for React app development. Whenever I make changes, three dots (an ellipsis) appear in the file and quickly shift the lines around. It is really annoying. How can I disable this behavior?

You can try deleting the GitLens or Git plugin. I resolved my problem this way.
Not sure if these are the same three dots (as on line 11)

But I disabled them with
"workbench.colorCustomizations": {
// other customizations
"editorHint.foreground": "#00000000",
},
