Created attachment 326025 [details] Screenshot of https://tobireif.com/demos/swirls/ in Safari. When I open https://tobireif.com/demos/swirls/ in Safari 11.0.1 (13604.3.5) on a MacBook (graphics: Intel Iris Pro 1536 MB) running Mac OS X 10.13.1 (17B48), I don't get the desired result as rendered by Firefox and Chrome. Instead Safari renders the animated sprites leaving fragments, please see the screenshot.
Also open http://www.goodboydigital.com/pixijs/bunnymark_v3/ in Safari and see the screenshot "screenshot_bunnymark.png". And Safari shows the issue for more PixiJS demos http://pixijs.github.io/examples/ eg http://pixijs.github.io/examples/#/basics/spritesheet.js .

Looks bad! I cannot reproduce this on my old MacBook Pro (13-inch, Late 2012); Safari 11.0.1 on macOS Sierra.

It's a MacBook Pro ("Retina, 15-inch, Mid 2015") with Intel Iris Pro 1536 MB.
The demos work as intended in Chrome and Firefox, on the same machine.
Do you see the issue on 10.13.2 betas, or in STP 43? From what I can tell in the code it looks like antialiasing is off. Can you try turning it on and seeing if it fixes it? If it does, 179368 is a dupe of this one.
Works in the latest Safari Tech Preview. Thanks! Please close. I hope it won't be more than a few days/weeks before the next browser update (containing this fix) will be pushed to users.
Works in stable/normal Safari now - thanks!
