Abstract: A method and an information handling system (IHS) renders a graphical user interface (GUI) from a remote device using a local storage. An interface controller detects a first event used to initiate access to the GUI at the remote device. The controller requests GUI frame buffer data corresponding to the first event, and GUI change data from the remote device. The GUI change data correspond to respective events that can trigger changes to the GUI. In response to receiving the requested data, the controller provides a first locally-rendered GUI using the GUI frame buffer data. The controller stores the GUI change data in local storage. The controller then detects a second event/interaction via the first locally-rendered GUI and retrieves from local storage a relevant portion of the GUI change data. The controller provides an updated locally-rendered GUI using the relevant portion of GUI change data.
