Description Robert Borghesi 2018-03-20 14:16:24 PDT
Hey there!
I was playing with SVG for experimenting some stuff and I decided to use and SVG filter applied via CSS to some different elements like div, img and form
Everything works fine in Chrome and Firefox but on Safari is messed up.
You can see a live version here www.operaomnia.mc and I created a codepen too here → https://codepen.io/anon/pen/MVJadQ
I thought was of a problem of my machine but I asked to many people and most of them see the problem, even on mobile

Here is a bunch of images of screenshot, machine info e safari version: https://imgur.com/a/XZgOa

This happens on Retina (2x) display only. A simpler test case is attached.

SVG filter versus CSS filter

This test case shows that the SVG filter works as expected while the CSS filter is not.
