I have done the following above but still having lagging issues. Although the lag appears to be much better in the terminal window. But every other window it's quite apparent after a few minutes of using the OS after a reboot. My Setup - 2 monitor driven by NVIDIA (`GA104M [GeForce RTX 3070 Mobile / Max-Q]) running driver `server-open::550.54.14` - 1 laptop screen driven by Intel graphics (`TigerLake-H GT1 [UHD Graphics`) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2059847 Title: Input lag or freezes on Nvidia desktops with X11 Status in Mutter: Fix Released Status in mutter package in Ubuntu: Fix Committed Status in mutter source package in Jammy: In Progress Status in mutter source package in Mantic: In Progress Status in mutter source package in Noble: Fix Committed 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.
