Bug ID: 183604
Summary: When the WebContent process is blocked from accessing
the WindowServer, the call
CVDisplayLinkCreateWithCGDisplay will fail.
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: WebKit2
Assignee: webkit-unassigned at lists.webkit.org
Reporter: pvollan at apple.com
When WindowServer access is blocked in the WebContent process, the function call CVDisplayLinkCreateWithCGDisplay in https://trac.webkit.org/browser/webkit/trunk/Source/WebCore/platform/graphics/mac/DisplayRefreshMonitorMac.cpp will fail. Should we call this function in the UIProcess, and send a message to the WebContent process for each refresh callback?
