45124 2010-09-02 12:56:53 -0700 [chromium] Gracefully switch over to software compositing when layer renderer fails to initialize 2010-09-03 16:24:49 -0700 1 1 1 Unclassified WebKit WebCore Misc. 528+ (Nightly build) All OS X 10.5 RESOLVED FIXED P2 Normal --- 1 vangelis vangelis fishd oldest_to_newest 273512 0 vangelis 2010-09-02 12:56:53 -0700 Currently if the accelerated compositor fails to initialize (e.g. failed to get a gl context), page renders without the composited layers. The correct behavior would be to switch over to software compositing. 273789 1 66470 vangelis 2010-09-02 22:36:55 -0700 Created attachment 66470 Proposed patch 274067 2 66470 fishd 2010-09-03 11:37:51

+ PassOwnPtr<LayerRendererChromium> layerRenderer(new LayerRendererChromium(gles2Context)); nit: this should be changed to use OwnPtr, like so: OwnPtr<LayerRenderChromium> layerRenderer(new LayerRendererChromium(gles2Context)); Then you should use the .release() method of OwnPtr<T> to finally return a PassOwnPtr<T>. > WebKit/chromium/src/WebViewImpl.cpp:2110 > + if (m_compositorCreationFailed) nit: I think the body of this function should just be changed to: return !m_compositorCreationFailed; R=me with those nits fixed 274250 3 vangelis 2010-09-03 16:24:49
