Public bug reported:
Guest OS running with GL enabled GTK display shows a reduced refresh
rate, e.g. moving cursor around with iGVT-g DMA Buf.
It seems that 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 should be applied to
display change listener or the default value should be used.
