  Mouse cursor stutters over GUI elements that are animated

Status in mutter source package in Jammy:
  Fix Committed
Status in mutter source package in Lunar:

Status in mutter source package in Mantic:

Bug description:
  [ Impact ]

  Mouse cursor stutters over GUI elements that are animated, such as GTK
  apps, web pages and shell elements.

  [ Test Plan ]

  1. Open Settings.
  2. Move the cursor up/down over an empty area of the desktop.
  3. Move the cursor up/down over the list pane on the left side of the 
Settings window.

  Expect: No difference in cursor smoothness whether the window below is
  animating in response to movement or not.

  [ Where problems could occur ]

  In frame scheduling, so the risk is more stuttering or screen freezes.

  [ Workaround ]

  Add this to /etc/environment:
  CLUTTER_PAINT=disable-dynamic-max-render-time
