Hi Daniel, No, not multi-GPU. It's an AMD system with no integrated graphics and only one Nvidia card. One monitor plugged in, one TV plugged in to that card via HDMI. But the TV is usually turned off, and disabled in Settings | Displays. Running Xorg, not Wayland.
This doesn't look like bug 1876632; it's not suspend- or VT-switch- related. Maybe I shouldn't have called it "corruption"; what I'm seeing looks like gnome-terminal just... deciding not to render something that it should; characters don't echo. No wild colors or randomized textures or anything like that. Seems like either a problem within gnome- terminal, or GPU command buffers just getting dropped on the floor. Awfully similar to this bug. -- 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?

[ 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.
