What are these white boxes for?

And how to remove them ?

Most likely the result of a linter plugin indicating some formatting or syntactial issues.

P.S.: Counter question: You save work in Sublime Text’s application directory within C:\Program Files\Sublime Text??? That’s dangerous! It gets lost upon next update of ST.

Ok. Thanks for the tip. I will save them in another folder.
