I believe that this Pull Request is trying to add this feature: https://github.com/dessalines/jerboa/pull/514

Hopefully it gets merged and then released, it would be nice to have this feature (that's how RIF behaved before)

At the moment blurring is kinda buggy:

It uses a Jetpack Compose function that is only available for Android 12 of newer. On older phones it just gets ignored.

I wrote a fix for older phones that has to be approved by Dessalines.

You can find the option to unblur in the settings
