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

[Jose Biosca]

The bug is still here.

People are simply modifying the code and recompiling.. It only needs to
change the code cap from 30ms (10 years old cap) to 16ms, and we got a
smooth gui capable of gaming.

Please, don't ignore us. Recompiling qemu only for one number is very
annoying.

Title:
  GTK display refresh rate is throttled

Status in QEMU:
  Expired

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.
