SVG can cause main thread rasterization via the path here . The call to GetDataSurface will flush the SourceSurfaceCapture to a temporary surface. Probably we should turn RGBALuminanceOperation into a Moz2D operation so it can be captured and replayed on the paint thread. This can be reproduced by loading layout/reftests/image-element/mask-image-element.html with d2d disabled and OMTP enabled.  http://searchfox.org/mozilla-central/rev/e76c0fee79a34a3612740b33508276f4b37c3ee8/layout/painting/nsImageRenderer.cpp#566
