So I've had my g3 for about 3 months and this has always been bugging me.Recently I installed the ressurection remix ROM,latest version, and everything is silky smooth except one thing which is present in stock too.Every time i type my PIN in there is a slight delay after pressing the numbers and when I'm playing a game which needs timed reactions e.g Jelly Jump, there is this really annoying delay,it's not choppy,laggy, just a delay like in my lockscreen.It recently fixed itself for like a minute or two and then it went back which annoyed the hell out of me. Any ideas on fixing this?

Any help is appreciated
