During the execution of a resize transaction, the buffer associated with a view's surface is saved and reused until the client acknowledges the resulting configure event. However, only one the main buffer of the main surface was stored and rendered, meaning that subsurfaces disappear during resize. Iterate over all, store and render buffers from all surfaces in the view to ensure that correct rendering is preserved.
