Hi Team, While going through Blink's commit, I came across another potential merge and I have tested this locally on --release build and does not seem to cause any issue. Although EWS or Debug builds might have other story to tell. NOTE - Motivation to merge is to get rid of "FIXME" and deadcode is deadcode: ____ Blink Commit - https://chromium.googlesource.com/chromium/blink/+/bd25c52a9a4dcd09e0ed47ba300cf82e86b28cb7 WebKit Source - https://searchfox.org/wubkat/source/Source/WebCore/rendering/RenderLayer.cpp#4480 ^ Removed: ClipRectsContext parentContext(clipRectsContext); parentContext.options.remove(ClipRectsOption::IncludeOverlayScrollbarSize); // FIXME: Why? if ((parentContext.clipRectsType != TemporaryClipRects && parentContext.clipRectsType != AbsoluteClipRects) && clipCrossesPaintingBoundary()) parentContext.clipRectsType = TemporaryClipRects; _____ Replaced: parentLayer->calculateClipRects(parentContext, clipRects); with parentLayer->calculateClipRects(clipRectsContext, clipRects); ____ Just wanted to raise to get input. Thanks!
