Created attachment 207735 [details] Testcase: Reference Screenshot Adding "-webkit-backface-visibility: hidden;" to a vector element (ex: Type) with "-webkit-transform: scale();" causes the scaled element to *not* be rendered at high quality. In other words, it's fuzzy. It's scaled up as if it were a bitmap image instead of a vector shape. Test Case: http://jsfiddle.net/ar_fiddles/aLVf8/ Browsers Tested + Results: Safari: All Fuzzy (bug) - 5.1.9 (6534.59.8) - 6.0 - iOS 6 Chrome (Mac/Win): 28.0.1500.71: Sharp (no bug) 28.0.1500.12 (iOS): Fuzzy (bug) (Not sure if this is related to it being the mobile version, or if a fix was introduced somewhere between xxxx.12 and xxxx.71) Firefox (Mac) - 22.0: Sharp (no bug) Related: "No anti aliasing on scaled elements when backface-visibility:hidden is set" https://code.google.com/p/chromium/issues/detail?id=144884 Possibly Related: "backface-visibility:hidden does not make RenderLayers, and should" https://bugs.webkit.org/show_bug.cgi?id=24435
