Windows 11 blur window bug
I just experienced this and I think it's related to the Windows 11 snap assist feature.
Whenever you drag an application to the top, bottom, or corners of a screen, a blurred overlay appears showing you the area it's being assigned to. I inadvertently experienced this when I locked my computer to walk away from it for a few minutes, blindly smashing the Win+L key (and likely other keys around it) until the screen locked. When I came back to my computer, the same blurred overlay appeared and I couldn't figure out how to get rid of it. Finally tried to move an application that was stuck behind it by alt+tabbing over to it and then pressing Win+right arrow to move it to a different screen. Once I did that, the blur disappeared.
Here's an example of the blur in action.
Yes, you're right! It's the snap assist. When I moved any window, the phantom blur snapped into another position. I shoved it around until it disappeared. What didn't work: restarting Windows Explorer or Chrome. I did not have to change resolution.
