Bug ID: 140400
Summary: Downloading web fonts causes unnecessary font
invalidation
Classification: Unclassified
Product: WebKit
Version: 528+ (Nightly build)
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Layout and Rendering
Assignee: webkit-unassigned at lists.webkit.org
Reporter: mmaxfield at apple.com
Every time a web font is downloaded, it calls CSSFontSelector::dispatchInvalidationCallbacks(), which increments m_version. This, in addition to RenderStyle::setFontDescription() always creating new Font objects, means that every time a web font finishes downloading, we throw out everything we know about fonts and regenerate everything.
