Agenda

• WebGL security (bjacob)
  • bug 656277: we're going to restrict WebGL textures to same-origin
  • We then want to relax this with CORS. Requires ImageLib changes.
• Text Rendering with DirectWrite (joe and a cast of thousands)
  • Overview
    • General concern that text rendering via DirectWrite is causing users not to upgrade, to leave FF or PR churn
    • Fonts with the largest issues are
      • Arial, Verdana, Tahoma, Times New Roman, Georgia
      • Font updates that were supposed to help not yet released by MS
        • Supposed to be out in April
    • We need both an interim solution and a longer term plan
  • Testing
    • http://people.mozilla.org/~jdaggett/tests/cleartype-waterfall.html
      • Needs to include non-Latin-1 text as well
    • about:config settings
      • gfx.font_rendering.directwrite.enabled = true
      • gfx.font_rendering.cleartype_params.*
        • rendering_mode -> -1/2
          • DW default vs GDI
        • enhanced_contrast -> -1/200
    • cleartype params in about:support
      • won't show up until you tune clear type in the control panel
  • Proposed interim solutions
    • GDI_CLASSIC flag for direct write
      • rendering_mode = 2
      • Affect about 34% of Windows 7 FF4 users
        • About 10% of user base (less because we still have a lot of 3.6 users, but they are migrating fast)
      • Possibly only for key fonts at certain sizes
    • Increase contrast
      • enhanced_contrast = 200
  • Proposed long term solutions
    • Test pilot study for feedback
    • More complete QA review on top websites
• Intern projects (joe)
  • We're looking for self-contained project proposals for interns to work on in September/January.
  • If you have ideas, please contact joe!
• bug 657141
  • 2x fps difference in for example speedreading
  • Backout or fix?
• Onboarding (Benwa)
  • bug 598425: Will be reading windows async code and investigating how to integrate the design on OS X.
• Cairo update
  • we are leaking a shared memory buffer the size of the window with D2D
