219594 2020-12-07 02:17:59 -0800 [GTK][WPE] Overflow/iframe scrolling with async scrolling enabled sometimes doesn't work 2020-12-07 03:31:26 -0800 1 1 1 Unclassified WebKit Scrolling WebKit Nightly Build Unspecified Unspecified RESOLVED FIXED https://bugs.webkit.org/show_bug.cgi?id=214179 InRadar P2 Normal --- 1 clord clord cgarcia cmarcelo ews-watchlist fred.wang jamesr koivisto luiz simon.fraser tonikitoo webkit-bug-importer zan oldest_to_newest 1712409 0 clord 2020-12-07 02:17:59 -0800 I dealt with this in bug 214179, but it turns out my implementation was flawed. It's possible for a descendent layer to contain a point that its ancestor doesn't, and this occurs very commonly with iframes (but not at all commonly with overflow scrolling). The Mac backend deals with this by just not doing any bounds checking, so we should do the same with nicosia. 1712410 1 415542 clord 2020-12-07 02:28:38 -0800 Created attachment 415542 Patch 1712412 2 415544 clord 2020-12-07 02:49:44 -0800 Created attachment 415544 Patch 1712424 3 ews-feeder 2020-12-07 03:30:03 -0800 Committed r270501: <https://trac.webkit.org/changeset/270501> All reviewed patches have been landed.
