Looks like it started at or around https://trac.webkit.org/changeset/266634/webkit (In reply to Ryan Haddad from comment #2) > Looks like it started at or around > https://trac.webkit.org/changeset/266634/webkit Hm, this change may affecting some layout tests, too: https://results.webkit.org/?suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&test=compositing%2Ftiling%2Ftiled-mask-inwindow.html&test=fast%2Fevents%2Fpage-visibility-iframe-move-test.html&test=pageoverlay%2Foverlay-remove-reinsert-view.html&test=tiled-drawing%2Ftiled-backing-in-window.html I already filed a bug about this and proposed a fix: https://bugs.webkit.org/show_bug.cgi?id=216258. About layout tests, I can only reproduce failure of fast/animation/request-animation-frame-throttling-lowPowerMode.html so far: https://bugs.webkit.org/show_bug.cgi?id=216261. *** This bug has been marked as a duplicate of bug 216258 *** (In reply to Sihui Liu from comment #4) > I already filed a bug about this and proposed a fix: > https://bugs.webkit.org/show_bug.cgi?id=216258. > > About layout tests, I can only reproduce failure of > fast/animation/request-animation-frame-throttling-lowPowerMode.html so far: > https://bugs.webkit.org/show_bug.cgi?id=216261. > > *** This bug has been marked as a duplicate of bug 216258 *** I can reproduce at least one of the failures.
