Is this Windows Phone 8.1 or Windows 10 Mobile?
In Windows Phone 8.1 she's still technically in beta and isn't on par in features or performance yet. She works just fine for the most part but every now and then she stumbles...a little more than every now and then actually. In Windows 10 Mobile (the official release) she's supposed to shed the beta tag and emerge as fully feature complete and extremely fast. However, major bugs like this...very weird. Have you done soft resets of your phone?
In Windows 10 Mobile...I wouldn't be surprised. It's still fairly buggy and incomplete and glitches like this are almost expected.
