Comment on attachment 417936 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=417936&action=review > Source/WebCore/ChangeLog:9 > + r271508 has a logic error that resulted in no scrolling thread layer commits, which meant that > + scrolling on pages with a busy main thread only updated layers at main thread cadence. Is a regression test possible? I'd have to write a bunch of infrastructure to test this (count layer commits on the scrolling thread). Committed r271637: <https://trac.webkit.org/changeset/271637> All reviewed patches have been landed. Closing bug and clearing flags on attachment 417936 [details]. |
