Abstract: Systems and methods disclosed herein provide a method of managing a state of a virtual rendering surface for an electronic document. The method includes obtaining, at a user device from a remote storage server, content relating to an electronic document, and rendering the content of the electronic document onto a first virtual rendering surface. The method further includes maintaining a second virtual rendering surface that stores a current state of the first virtual rendering surface. The method further includes obtaining an operation command relating to the electronic document, and retrieving first state information of the first virtual rendering surface and second state information of the second virtual rendering surface. The method further includes applying the operation command to the rendered content of the electronic document on the first virtual rendering surface, and updating at least one of the first state information or the second state information based on a type of the operation command.
