This occurred after a fresh reboot this morning, after letting my displays go to sleep for ~5 minutes. dmesg log also attached. The IO_PAGE_FAULT entries begin shortly after moving my mouse to turn the displays back on.

It's still possible to interact with the windows below this layer, but it's not possible to see what's happening without moving them to a display that doesn't have this glitch. This occurs in both x11 and wayland sessions, and it's new on noble (didn't see it on mantic, including with the backports ppa).
