All streets got blue in Google maps??

Hi guys, not sure if it's the right place to ask but I'll try it anyway. All of the sudden Google maps turned all streets blue on my laptop and it doesn't go away!! I'm in the standard mode (not street view), I haven't changed any settings... I have tried cleaning the cookies, but it didn't help. If I sign out or use Google Maps on my smartphone, the normal design is back again. So the problem seems to be only in my account and only while using laptop.... Did anyone have such a problem and have a solution?
