[Qemu-devel] [Bug 1802915] Re: GTK display refresh rate is throttled

[Thomas Arouge]

Instead of changing the value, I think there should be a function that
determines the ideal "GUI_REFRESH_INTERVAL_DEFAULT" value, with the
option to override it. That way, monitor greater than 60 Hz can also
benefit.

Title:
  GTK display refresh rate is throttled

Status in QEMU:
  New

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.
