Apparently, a default refresh interval GUI_REFRESH_INTERVAL_DEFAULT (30ms) is defined in include/ui/console.h, throttling the display refresh rate at 33Hz. To correct this throttle issue, a shorter interval (16 or 17 milliseconds) should be applied to display change listener or the default value should be modified.
