Nautilus 43.4 displaying outlines of application window

HI there,

I am running Gnome 43.5 and Nautilus 43.4.

I have for some time (since Gnome 43 onwards) had an odd fuzzness around the application window. There are rendering issues and square border outlines around the program itself which appear (see below).

Currently I dont have any extensions on nautilus other than sushi.
