Abstract: An example electronic device may include a display, a processor, and a memory. The memory may store instructions which, when executed, enable the processor to: execute a first application providing a stereoscopic screen; store, in a first frame buffer, a first execution screen generated by rendering a screen provided by the first application; while the first execution screen is being displayed, identify an execution request of a second application providing a non-stereoscopic screen; execute the second application in response to the execution request of the second application; store, in the first frame buffer, a second execution screen generated by rendering a screen provided by the second application; store, in a second frame buffer different from the first frame buffer, a third execution screen generated by stereoscopic-rendering the second execution screen; change a frame buffer referred to by the display from the first frame buffer to the second frame buffer; and display the third execution screen.
