Bug ID: 197002
Summary: Defer rendering in pinch to zoom
Product: WebKit
Version: WebKit Nightly Build
Hardware: PC
OS: Linux
Status: NEW
Severity: Normal
Priority: P2
Component: WebKitGTK
Assignee: webkit-unassigned at lists.webkit.org
Reporter: raffaele.tranquillini at gmail.com

Pinch to zoom currently renders content while the gesture is being performed, at every single step, making it laggy on mildly complex pages. The rendering should probably be deferred or triggered in larger zoom "steps" while being combined with cached and scaled previous rendering buffers. Does Safari handle this differently than on Gtk? It looks way smoother even on less powerful CPUs.
