Ubuntu 21.04 icon issue after distribution upgrade

Ubuntu

Good morning,

Yesterday I upgraded Ubuntu OS from 20.04 to 21.04. After installation, I found an issue with embedded icons in wallpaper that seems part of the image without any use. If I change the wallpaper those embedded icons are still there.

Anyone has this issue and know how to solve it?

Thank you in advance.

Welcome aboard.
Given what you’ve described so far I’m thinking screen burn. I had the same issue with my cell phone just recently.
Are they still there if you open a document?
Are they faint or prominent?
Can you delete any of them?
