Hey guys... hey Daniel,

Do you guys know when the fix will officially be available for 22.4.04
LTS? Is it expected in the next few days or weeks, or will it take a
long time to happen?

Thanks a lot!

Title:
  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.
