Slow text on screen.
I'm touch-typing now and it's fine. i.e. while on the pprune screen.
W10 on i5
However, FF 58.0.2 with Google as home page, text is taking an age to follow my input in say, the search box. An age is about 1 - 2 seconds, but I'm waaaaaaaaay ahead in that time.
I've just found my Word is okay, thank goodness. So is Explorer, erm Edge. So, it seems it's just doing it with FF and the Google input. Odd.
I've had it before, but just can't remember what it was. I do not have many add-ons. Almost none, and I've killed those.
Now I know it's so localized I realize I've been looking in the wrong places, but anyone know right off the cuff what it is?
