Default Screen & Home button don't function

After installing Kitkat on Note 3 lte I noticed that the screen freezes and doesn't respond to finger touch. Also the Home button doesn't respond to finger pressing. I have to use S-Pen instead. After a few minutes the note 3 becomes normal... Could it be the Kirk rom that causes it... I'm open to all suggestions except taking it to the service center because of warranty void.. Thanks in advance...
