Minutes:

• (no need to discuss, just FYI) http://people.mozilla.org/~bjacob/gfx_features_stats/
  • Seeing unexpected noise in webgl results, (weekend variation?)
  • 300k crashes/day; 4k using WebGL
• WebGL conformance (bjacob, dsherk)
  • Test suite update finally landed last week
  • dRdR has fixed 5-ish bugs
  • Remainder of the bugs discovered by the new test suite are being sorted out quickly
  • Test suite seems to be of much higher quality: fewer intermittent oranges, better testing
• WebGL antialiasing (jgilbert)
  • Running into 2 crashers, one with ANGLE, one with WGL
  • bjacob recommends we land preffed off
• SoftwareRasterizer (for mobile) (Bas, mwoodrow)
  • Quick and dirty software rasterizer (faster but lower quality than pixman)
  • mattwoodrow notices that there seems to be a lot of things that are blocked on content drawing speed
  • Layout doesn't use layers optimally right now
  • Curve flattening, data structures, etc can potentially be re-used for Emerald
  • jrmuizel suggests we try Skia first, since it's fast
• D3D9 regression (BenWa)
  • Reproduced the regression intermittently by using the Talos tp4.manifest file. Not sure what the best way to proceed.
• GL Layers on Android (ajuma, benwa)
  • Working on getting talos numbers for turning on the feature. No change seen when landing this on however the feature was correctly turned on.
  • Working on a user space profiler. So far we seem to be getting accurate numbers. Ehsan is adding a GUI and further instrumentation is required.
  • Black flash on orientation change and resume. Should also fix crashes. Let us know if you're seeing crashes.
• heeen's update for GL layers on mobile
  • Working on scrolling
    • Awesomebar, history much faster
    • Performance problem with scrollbox with the batch size attribute
    • Glitches with the URL bar. Layer conflict problem?
    • Out-of-place URL bar on Maemo, similar to problem we had with Android.
• Testday last Friday, August 26 (joe)
  • Testday metrics
  • 15 bugs triaged
  • Joe also did two videos as part of being a "guest developer" on the test day:
    • Introduction to triaging and verifying an assertion bug on Windows
    • An addendum to that for OS X and Linux
  • Other developers who would like to be guest developers are wanted! Contact Matt Evans or Anthony Hughes about participating.
• Synthetic Bold Ownership (jpr)
  • bug 674909 - there's a question about how we're using Cairo
  • Bas to make helpful comments on the bug and ask if John's blocked on anything
• Demos and Talks (jpr)
  • Tell JP if you have ideas for demos or lightning talks
