WOW! Weird Bug!

[anon(9057135)]

I was on IE and it crashed and my phone looked like this for like 10 seconds. If you can't tell, it's Cortana and the navigation bar.

Looks like the same bug I had back in 8.0 gdr2/gdr3 days.
But it was fixed for me since Black firmware. But it could also be that I don't use IE much anymore and don't notice it.
