Description

When I use TwentySeventeen with Firefox (50.0.2 for Ubuntu) I get this warning on the front page in my console:

This site appears to use a scroll-linked positioning effect. This may not work well with asynchronous panning; see https://developer.mozilla.org/docs/Mozilla/Performance/ScrollLinkedEffects for further details and to join the discussion on related tools and features!

Does not happen with TwentySixteen or in Chromium.

#38850 is related as it is about same warning, but is happening in the editor.

  • Keywords needs-patch added
  • Milestone changed from Awaiting Review to Future Release
  • Summary changed from TwentySeventeen Warning in Firefox console. to Twenty Seventeen: Warning in Firefox console for scroll-linked positioning effect.

Thanks for the report @Shelob9! This is only a warning, so I'm not too worried about it. But we might be able to adjust the JavaScript to avoid the warning and be more performant. It's worth further investigation. Any patch will need to be mindful of the theme's current browser support and not breaking any existing sites.
