Featured images on category page look blurred when I resize the screen in Chrome. Changing the septera-featured size doesn’t help. It is weird because when I switch to another WordPress theme, renegerate thumbnails and go back to Septera then fetured images on category page look perfect. I don’t understand this behaviour and how it actually works. Is it possible to remove septera-fetured size and show oryginal pixel size in excerpts? Need help.
