I am seeing similar interactivity issues on fully updated 22.04 on a Dell Precision laptop with Nvidia + X11 that started a day or so ago. Most noticeable in the terminal with lag/stuttering and seemingly lost keyboard inputs, but also affecting other apps with stuttering keyboard inputs and sometimes seemingly lost mouse clicks.
