Created attachment 258714 [details] Gif demonstration of the issue Hi, Issue: The Blur generation catches other windows into the blur generation when used in -webkit-backdrop-filter How to reproduce: I made a very simple example : http://mathieuhays.github.io/Backdrop-filter/ Open the inspector on a separate window. Position it above the blurred part. Toggle the css property -webkit-backdrop-filter off and on again. Move the inspector out of the way. You should see that the inspector window has been included in the blur rendering.

I can't reproduce on Yosemite. What OS, hardware and WebKit revision were you seeing this on?

I tried on both iMac and macbook on OS X 10.10.5 Webkit version 8.0.8 (10600.8.9, r188304) I noticed that the issue also happens when you refresh the page with the inspector focused and on top of the blurred part. http://recordit.co/kDeQXwCb7J

I just tested again in the latest Safari version and it's now fixed
