Title:
  Animations stutter constantly on Nvidia in GNOME 40

Status in Mutter:
  Fix Released
Status in mutter package in Ubuntu:
  Fix Released

Bug description:
  [Impact]

  Animations stutter constantly on Nvidia in GNOME 40.

  We're missing:
  https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1826

  [Test Plan]

  1. Run glxgears and maximize it.
  2. Watch closely.
  Expect consistently smooth animation.

  [Where problems could occur]

  Since the fix touches on frame scheduling it could (and should) affect
  the smoothness of the entire screen. Although it is designed to only
  affect drivers that have `frame_clock->last_presentation_time_us ==
  0`, so that's the Nvidia proprietary driver and maybe some virtual
  machine configurations.

  [Other Info]

  The upstream fix mutter!1826 is mutter 41.0 onward, and now in 40.6
  onward. So we can drop the patch as soon as 40.6 is ready.
