Flash Player version 15 (FP 15) introduced a feature whereby the loss of sharpness of Stage3D content upon browser zoom can be avoided. With prior versions of FP, upon the user’s changing of the browser zoom factor, content that is rendered to a statically sized Stage3D buffer is scaled to match the browser zoom. As the browser zoom factor increases, the sharpness of the Stage3D content is increasingly lost due to the scaling content. A new functionality introduced in FP 15 provides an event notification to the content when the browser zoom changes, and allows the content an opportunity to change the size of the Stag3D back buffer and re-render the stage3D content.

This feature is extended to support the Firefox browser with Flash Player Version 21 (FP21).
