HTC One - jumping, flickers, swapping, opening, closing apps

[AC Question]

Hi,
Has anyone else had a problem where the HTC one keeps jumping, flicking between app pages, opening and closing, pressing the home button doesnt work to stop it. have to press the lock button and leave a few minutes then unlock and hope the problem has fixed. Ive re-started many times and this doesnt seem to work. this happened about one month ago - but since fixed itself. has been happening all day today and nothing seems to fix it.
help
