Locating when it started for you would be valuable, even if it's not pin-pointed such as a git bisection could do. A bisection is the best bet to nail it down, but can be quite time consuming.
One thing you can try is to drop to a non-gui shell, and see it the symptom is reproducible without the GUI. If it is, poke SysRq-W while things are thoroughly jammed up, and post the output+config here.
