Status Bar/Notification Bar Problem

[GohKaixuan]

The line, clock and date is missing from the screenshot, this happens not so frequent but so far twice... But after a while it seems to come back... Is there some kind problem? While typing this post the clock and date reappears. . http://postimg.org/image/lwapzjokf/
