Slow login screen

So I go to get a cup of coffee, take a break. When I get back my screen has timed out - wiggle mouse - nothing. Hit Enter - onethousandone, onethousnadtwo, … ten and there’s the login screen.

And I set Focus under Mouse. Only there seems to be a invisible frame ?10%? of of no-mouse. Also grabbing top bar to drag → MENU, no! Then in the window click, click, click - now drag works

Just saying
