Besides snapshotting right before a lost context doesn't help us at all. For all we know the GPU could be half way through rendering something when the event is triggered... even if we could read back the half rendered content in the rendertarget how do we generate the correct output from there? We'd have to take our DeLorian back to before the frame was started and replay the rendering commands. -- Erik Möller Core Gfx Lead Opera Software twitter.com/erikjmoller
