Issue descriptionUserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_2) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/12.0.2 Safari/605.1.15 Example URL: https://blog.tumult.com/wp-content/uploads/2018/vectorcontestwinners/9%20months.html Steps to reproduce the problem: Simple large blurs can have graphical corruption. This is evident with simple code: <html> <body> <div style="background-color: rgb(255, 235, 200); width: 450px; height: 446px; filter: blur(79px);"></div> </body> </html> Or this URL: https://blog.tumult.com/wp-content/uploads/2018/vectorcontestwinners/9%20months.html What is the expected behavior? Blurs should work at any size. What went wrong? The blur is graphically corrupt. Please see screenshots. Does it occur on multiple sites: Yes Is it a problem with a plugin? No Did this work before? N/A Does this work in other browsers? Yes Chrome version: 73 Channel: canary OS Version: OS X 10.13 Flash Version: If you turn on a "transform:rotateY(0deg)" it seems to work, but this is not an acceptable solution as our tool (Tumult Hype) encounters other bugs (which have been reported) with this method. It seems to work correctly on macOS 10.14 on a different machine for me, but not macOS 10.13. Also tested on a windows machine and it was fine.

I can't reproduce this and it seems likely to be GPU issues. Please open chrome://gpu and paste the contents in here.
