GTK display refresh rate is throttled

Guest OS running with GL enabled GTK display shows a reduced refresh rate, e.g. moving cursor around with iGVT-g DMA Buf.

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 milliseconds) should be applied to display change listener or the default value should be modified.

The gamer community that uses qemu are recompiling only for change that value, and we got a really smooth gui. At least it would be nice to have a config parameter for that value.
