Created attachment 287673 [details] overflow-transform-filter-bug-demo.html A combination of transform property on a parent element, with an overflow: hidden and filter properties on the child, causes the child to be entirely invisible. See either the attached html or the following jsbin for demonstration http://jsbin.com/botekiradu/1/edit?html,css,output. Bugs present in Safari Tech Preview Release 12 (Safari 9.1.2, WebKit 11603.1.3) and iOS 10 betas. This seems like a regression as the issue isn't present in the current stable release of Safari or iOS9.
