Default [Q] Moto g-Blue lines on statusbar, on some apps

Hi everyone! I bought my Moto g 2 Months ago and I didn't notice anything strange. Now when use Google Chrome Beta, FB, MusicXmatch etc. I can see blue lines on the top of the screen. The more time I use the apps the more blue the screen becames. Also do you think that the warranty covers such problem(The phone is not rooted-Yet!). Thanks in advance! (When I return home I will post how it looks like)
