Since there was "No Change" in the official version, can Daniel quickly
bump the version of his TEMP fix to "42.9-0ubuntu7.1vv1" (or equiv) so
it becomes the latest again and we can wait for the next update?

  Input lag or freezes on Nvidia desktops with X11 after logging
  "MetaSyncRing: Sync object is not ready -- were events handled
  properly?"

Bug description:
  [ Impact ]

  Input or the entire screen may freeze at times on systems using the
  Nvidia Xorg driver with GNOME.

  [ Test Plan ]

  0. Set up a desktop with Nvidia driver 545 or 550.
  1. Log into Ubuntu, ensuring it's a Xorg session.
  2. Open a Terminal, resize it vigorously, and type several lines of text.
  3. Run: journalctl -b0 | grep MetaSyncRing
  4. Verify the above command does NOT show "MetaSyncRing" messages such as:

  Window manager warning: MetaSyncRing: Sync object is not ready -- were events handled properly?
  Window manager warning: MetaSyncRing: Sync object is not ready -- were events handled properly?
  Window manager warning: MetaSyncRing: Sync object is not ready -- were events handled properly?
  Window manager warning: MetaSyncRing: Too many reboots -- disabling

  [ Where problems could occur ]

  Anywhere in Nvidia (proprietary driver) Xorg sessions since the code
  being modified is only used with that driver.

  [ Original Description ]

  There is a noticeable delay in input while using the native terminal.
  I belive it was caused by a recent software update, as this issue is
  relatively new.
