Strange rectangles on desktop background

My MacBook Pro's desktop background has these strange rectangles that I've never seen before. At first I thought it was showing up in the image itself but it's still there when I change to different desktop images. It's not a screen display issue because I can cover it up with windows like Finder and Firefox. I can't drag or do anything to the shapes.

Has anyone else had this issue? Does anyone know a solution? Here are some screenshots to show what I'm talking about.

Original desktop background, rectangles in lower-right section:

With a basic color background:

Clicking the background and highlighting over the rectangles doesn't affect them:

With a stock background image:

Covering the rectangles with the Finder window:

MacBook Pro, macOS High Sierra (10.13.3)

Any of the zoom options turned on inadvertently?

System Preferences > Accessibility > Display > Zoom > Options

> Show preview rectangle when zoomed out

Disable it, if it is enabled. Click"OK"

Hey everyone, thanks for the input. I shut down my laptop and turned it back on and the rectangles were no longer there. They haven't reappeared since.

I'm still not sure what caused them to be there in the first place. I didn't have any of the Zoom options on. Unfortunately I didn't try Safe Mode to see if that would have changed anything.
