[chromium] Only initiate the beginFrameAndCommit sequence if a commit has been requested
https://bugs.webkit.org/show_bug.cgi?id=68967
Patch by James Robinson <jam...@chromium.org> on 2011-09-27
Reviewed by Kenneth Russell.
When updating the scheduler state, we should only initiate a new commit flow if a commit has been requested (as
opposed to only a redraw).
Covered by the unit test CCLayerTreeHostTestSetNeedsRedraw with USE(THREADED_COMPOSITING) set to true.
* platform/graphics/chromium/cc/CCThreadProxy.cpp:
(WebCore::CCThreadProxy::updateSchedulerStateOnCCThread):
