+ [ 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 that's the
+ code being modified.
+
+ [ 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.
