Bug ID: 186914
Summary: [WPE][ThreadedRendering] WPE crashes rendering SVG
content when using ThreadedRendering
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: WebKit WPE
Assignee: webkit-unassigned at lists.webkit.org
Reporter: magomez at igalia.com
CC: bugs-noreply at webkitgtk.org
Some SVG content uses GraphicsContext::clipToImageBuffer to define a clipping from the contents of an ImageBuffer. But GraphicsContextImpl doesn't have an implementation for this method so the call cannot be delegated and recorded. Instead, cairo GraphicsContext tries to perform cairo operations while in the recording state which causes the crash.
