What is this rectangle and how to delete it?

[libre_office_user]

I was pasting links into a document and this giant rectangle appeared. It had a red play button on the bottom right corner, but then that disappeared.

• What is it?

• How do I delete it?

Thanks!

It is very hard to tell from a screenshot (and without details such as OS name, exact LO version and save format). And you didn’t enable View>Formatting Marks which have given potential clues about the rectangle contents.

My wild guess is a frame (or blank image) is hovering over your text. Have a look at the Navigator in the right side pane (or make it visible). See if there are “objects” in the Frames or Images sections.

For best diagnostic, attach the document, at least the offending page if it is larger than the allowed limit.
