Created attachment 270906 [details] Reproduction of the bug I've been getting blurry fonts and images from this peculiar compositing bug. It occurs when two or more nested CSS3 perspectives are applied and a <meta> tag with content="initial-scale=1" and/or content="width=device-width, height=device-height" is applied. If either perspective is turned off, the blurriness is gone. If the meta tags are removed the blurriness is gone. Even if the initial-scale is set to any number besides 1, the blurriness is gone. It has forced me to remove one of the perspective styles for my site on mobile http://samsarajs.org

Happy this has been fixed, but sad that it languished for over a year before being rediscovered by an employee and then immediately fixed. This pattern is unfortunately the norm in my experience.
