Describe the feature you want

I thought it would be nice if the lock screen background could be blurred instead of being purely focused.

Is your feature request related to a problem? Please describe it

Additional context

How will you/everyone benefit from this feature?

Usually, the thumbnails are not in a very good quality by default, and so the background does not always look very nice. If the background was blurred, the defaults would not be noticed, and it would give a cleaner aspect.

I would like to try to handle this. I need some time I will add this.
