Enable OpenGL layers on X11	Functionally complete, assessing risk of regressions	mid-May	Matt Woodrow

Summary

This feature is enabling OpenGL compositing of layers on X11 systems. We already have this on by default on OSX, and are working towards it for mobile.

Team

Who's working on this?

• Lead Developer: Matt Woodrow
• Product Manager: unknown
• QA: unknown
• Security: unknown

Release Requirements

• Needs to pass all reftests tests on mozilla-central.
• Needs to not regress talos benchmarks on tinderbox.
• Needs to not regress perceived performance for users.
• Needs to not regress stability for users.

Next Steps

• Get testing coverage of this configuration on tinderbox. bug 594876
• Flip the switch on mozilla-central and measure amount of new bug reports.
• Adjust blacklisting and disable the whole feature if necessary.
• Adding new performance tests for regressions would be useful.

Related Bugs & Dependencies

Designs

Do we have accelerated layers design docs anywhere?

Goals/Use Cases

Improve the performance of the scrolling and compositing of complex pages on X11 without regressing performance or stability on other pages.
