#39GTK3: hikari border and window don't match in their position

This cosmetic issue exists since quite some time. I first noticed it with apps from GNOME, but now it appears in more and more unrelated programs, that use GTK3.
The issue itself is, that the border around a window which gets drawn when pressing super has an offset with the actual window.
