After a bit of poking around, this is perhaps a kernel bug that is fixed in 4.4.8

You could try upgrading your kernel if you're feeling adventurous. If that is the issue, it will probably be backported at some point though.

Cool, I'll wait it out as it isn't really an issue for me, thanks for helping out though, it's really appreciated!
