In 307177@main we added a dedicated setting to control whether high frame rate can be used to update animations at all. But even if this setting is enabled, we need to be smart about what to update at a high frame rate. An obvious first step is not opt `opacity` and `filter` animations into high frame rate such that only transform-related animations qualify. 2180305 1 webkit-bug-importer 2026-02-11 09:29:33 -0800 <rdar://problem/170153252> 2180309 2 graouts 2026-02-11 09:37:47 -0800 Pull request: https://github.com/WebKit/WebKit/pull/58412 2180660 3 ews-feeder 2026-02-11 22:58:38 -0800 Committed 307339@main (de8c3e0c5b15): <https://commits.webkit.org/307339@main> Reviewed commits have been landed.
