In bug 1109718 we've run into problems with IDXGIKeyedMutex invalidating the RenderTargetView on some machines. Instead of recreating the RenderTargetView we could use the new SyncObject infrastructure added in bug 1088414. Not only will this avoid having to recreate the RenderTargetView but it will also avoid the extra flushes that using a IDXGIKeyedMutex causes. This should improve performance when we're drawing anything more than just the canvas.

I still don't have a good idea of what this should look like...
