application blur disabled in overview
this may have been on purpose, but I feel it would look a lot better if the applications were still blurred in the overview

This is of course not on purpose, but I don't know how to do this :) I will try more when I have some time!
No worries at all. For sure :)
It's a lot better now, thanks! The issue now, however, is that it is blurring the same region of the screen the window refers to when it is not zoomed out by GNOME's overview.
In overview:

Outside of overview:

Hello, I know the blur position isn't right, but I can't do much about it for the moment... As the original bug is fixed, I close this issue; and the issue you described is now in #375.
