Thank you for any help.
Probably due to some extension you're using, maybe a linter. Does the status bar give any hint what's going on when the cursor is inside a bordered section?
Yeah! You were right and the problem was solved it was Sublime Linter, I have deactivated it and everything is ok.
Thank you very much.
