Title:
GTK display refresh rate is throttled
Status in QEMU:
Confirmed
Bug description:
Guest OS running with GL enabled GTK display shows a reduced refresh
rate, e.g. moving cursor around with iGVT-g DMA Buf.
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.
