Shutdown, no appcrash, but resolution restore to 1024x768 after next boot.[[BR]]

and some not expected behaviour, case: host 1440x900, guest 1024x768[[BR]]

first enable auto-resize then fullscreen then scaled mode, now guest is 1440x900, then restart, resolution restore to 1024x768 after next boot, doesn't it should be 1440x900?[[BR]]
