GFX

• We think that OpenGL ES accelerated layer composition on Nightly builds for Android is ready to be tested by technical users.
  • There are still some known minor rendering glitches when pinch-zooming or panning; single frames are drawn at the wrong scale.
  • To turn it on, set layers.acceleration.disabled to false and layers.acceleration.force-enabled to true in about:config, and restart your browser.

Layout

• More 3D transforms stuff landed, some more to come before we can try turning it on by default (mattwoodrow)
  • Discovered an interesting regression on Facebook where they feed -webkit properties to any browser that Modernizr says supports 3D transforms :-(
• Jonathan Kew persuaded some authors of TeX hyphenation dictionaries to relicense their dictionaries to be a bit more liberal, so we will ship dictionaries for some more languages

• Team status:
  • dbaron: review hell, investigating mobile text resizing
  • dholbert: CSS3 flexbox

  • jwatt: converting SVG code to use display lists and be more like other layout code
  • heycam: WebIDL, reworking SVG text to use CSS layout
  • smontagu: implementing and unicode-bidi:isolate

Video

• Landed support for temporal media fragment URIs (e.g. http://example.com/video.ogg#t=10,20) (doublec)
  • UI piece (changes to built-in controls) still needs to land

• Team status:
  • doublec: bug fixing

Roundtable

• Guest developers for test days (joe)
  • Joe Drew did two videos as part of being a "guest developer" on last Friday's test day:
    • Introduction to triaging and verifying an assertion bug on Windows
    • An addendum to that for OS X and Linux
  • Others who would like to be test day guests are wanted! The idea is to explain things about your workflow, how to do something that might not be obvious, or any other thing you might want to show to our triagers and testers.
  • Contact Matt Evans or Anthony Hughes about participating.
