GFX Priorities Minutes

This meeting was scheduled to discuss priorities for the graphics team.

Note: Only had representation from perf (Taras). GFX team has a good idea of what to do next on mobile. Need to follow up with Andreas Gal/Chris Jones for B2G.

OMTC

• plugins drawing completely off main thread
  • plugins post frames directly to compositor
  • path for core animations misses all optimizations as it's basic, mostly an OSX issue
  • can add intermediate step but would prefer to do it right from the start

• can work on stabilizing OSX and Linux while starting Windows work

• refactoring layers would push out OMTC weeks to months but give us better code
  • composition and validation should be broken up
  • this work will make Firefox faster when done

• [action] Joe will draw up omtc roadmap with milestones, should be ready next week

• Can we get OMT throbber and CSS animations by the end of the year?
  • maybe on central by then but qualified to a specific backend

• will be cheaper to work on one platform at a time
  • expecting portability concerns for individual features across backends in order to keep all of the fast paths

• don't know how long the layout side of css animations will take

• BenWa has seen talk about async canvas, not a viable option

• BenWa suggests getting better profiling data on janks to get short term solutions
• Bas has a plan to fix some of this

• borders in chrome, why no use images?
  • borders also used heavily in sites like google so fixing in chrome doesn't really fix the problem, front-end team also resistant

• Bas can turn on azure in two weeks for direct2d
  • still don't retain gradients
