Default [Q] slimsaber question...

Hi everyone. Just a simple question here since I'm only a junior member and can't post in dev threads... I've been using fusionjack's slimsaber for the past few weeks and its amazing! Been through the dev thread and haven't seen anyone mention this, but many times after closing an app, the app which was previously running flashes for a second before closing. Am I the only one experiencing this? Been happening since I started using this ROM last month. Currently on 1/18 build with apolo kernel...thanks!
