Lock screen buttons stuck on navigation bar topic

So... After 30 minutes of use. The little lock screen arrow and camera buttons appear on the navigation bar. Can't use home or back. Have to reboot.

Any ideas?

Rooted Dev edition. 4.4.2

Everything else works 100% fine

Using xposed and gravity box. Just removed it to test.

Any one run into this?
