Summary: Crash possible when switching scrollbar appearance
preference on Mac
Product: WebKit
Version: 528+ (Nightly build)
Platform: Unspecified
OS/Version: Unspecified
Status: NEW
Keywords: InRadar
Severity: Normal
Priority: P2
Component: Layout and Rendering
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: bdakin at apple.com
A crash is *still* possible when switching the scrollbar appearance on Mac because the current mechanism that is intended to flag ScrollAnimators as being in the page cache or not does not work correctly. Long-term the fix for this is to move the ScrollabelArea HashSet to a more appropriate place -- it's on Page right now, but instead it should be on another class that represents a single web page. Something like the top-level Document. In the meantime, I have a patch that fixes the crash.
