- Ubuntu 22.04.4 LTS (5.15.0-56-generic)
- I am using X11 when nvidia driver is in use.
- Checked via observing `XDG_SESSION_TYPE` variable
- I am using on-demand feature for nvidia but switching to performance mode
only does not help.
My primary issue is keyboard input lag. It is not as bad as it used to be but
it exist.
- I notice it in terminal window and vscode as these are the applications I use
mostly
- Sometimes it take a few minutes to appear after a reboot sometimes it appears
right away.
Other than the keyboard input lag I notice some lagging when scrolling
in Chrome. However this is less apparent.
I can't downgrade nvidia driver, this is likely an unrelated to this bug though.
- Debian package manager just install nvidia 550 regardless of the package I
choose.
- `ubuntu-driver` think drivers are already installed if I try to install a
specific version.
- `ubuntu-driver` autoinstall/install just install 550

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. Verify that input never froze for any perceptible period of time.
4. Run: journalctl -b0 | grep MetaSyncRing
5. Verify the above command does NOT show 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.
