    Performance Issues in Flash 30.

      We are getting reports from users throughout the Scratch (scratch.mit.edu) community of performance issues related to Flash 30. Upon a deeper investigation it seems as if the main event loop is running much more slowly even in simple tests, this may have something to do with hardware (GPU) acceleration, but more investigation is needed. Results of a single benchmark for Chrome on MacOS are included below, but we are seeing the impacts of these across all 200+ million projects shared in the Scratch online community. We have also been able to repro this on Firefox and Safari on MacOS. We will be testing on Windows shortly and will post results here once complete.
