As usual, WebRender is making rapid progress. The team is working hard on nailing the remaining few blockers for enabling WebRender in Beta, after which focus will shift to the Release blockers . It’s hard to single out a particular highlight this week as the majority of bugs resolved were very impactful.

Notable WebRender and Gecko changes

  • Kats fixed a parallax scrolling issue.
  • Kats fixed the trello scrollbar jumping bug.
  • Kats fixed a crash.
  • Kats fixed various other things .
  • Matt finished the work on shader compile times. The startup times with and without WebRender are now on par.
  • Lee made WebRender more aggressively clean up evicted font instances in the font backend.
  • Lee fixed a bug with Windows variation fonts.
  • Emilio fixed some pixel snapping issues with fallback content.
  • Emilio fixed filter and fallback scaling issue.
  • Glenn fixed nested scroll frame clipping.
  • Glenn fixed large SVG clipping on google docs.
  • Glenn made various refactorings towards picture caching.
  • Glenn reduced the amount of work we do when building clip chain instances.
  • Nical added support for applying filters in linear space to WebRender.
  • Sotaro avoided scheduling repaints during animation if the animation values haven’t actually changed.
  • Sotaro fixed a frame scheduling bug.
  • Sotaro fixed a crash with cross process texture synchronization on windows.

Ongoing work

  • Bobby is improving memory usage by figuring out what set of OpenGL incantations with which planet alignment don’t cause ANGLE to opt into mipmapping where we don’t need it.
  • Chris and Andrew are looking into why we aren’t getting as much data as we hoped from the latest shield study.
  • Gankro making progress on blob recoordination.
  • Nical is adding support for running a subset of SVG filters on the GPU (instead of falling back to blob images).
  • A confabulate of graphics folks are thinking very hard about frame scheduling strategies to avoid uneven frame rates when certain parts of the pipeline are struggling.

Enabling WebRender in Firefox Nightly

  • In about:config set “gfx.webrender.all” to true,
  • restart Firefox.
