Default [Q] scoll speed issue

Hello guys.So before i start,i'm sorry if i'm in the wrong section.I'm an owner of a galaxy core i8260 and i'm not dissapointed by its overall performance.Since yesterday though my scrolling speed changed.Its so slow,it's really annoying.So to be clear,i dont mean the smoothness,I mean the SPEED.Here's an example:when i open my music app,it takes ages to scroll down to my whole list since the scrolling is amazingly "heavy".Is there anyway to change the scroll speed?In case that helps,my phone is rooted and i have pimp my rom installed(im running the stock rom)
