threadbareobserve, the nvidia driver can be downgraded to 535 without too much work. I'd make sure all the related packages are removed before installing 535.
Might help the developers to know what version of Ubuntu you're running. I'm running a 22.04 desktop with a 4070 card, and the PPA does *not* fix the problem for me. It removes the lag, but that means the corrupted screen just happens faster. This is a bit intermittent and hard to pin down, but I've particularly noticed this after attempting to paste text into Gnome-Terminal; only the first few pasted characters might be echoed, then it gets into a state where keyboard input is processed but not all of it is echoed. -- 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?

[ 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.
