XPS 15 9500, Function Key problems

Question

Hi everyone. I recently got an XPS 15 9500 and had no problems with it for the first couple of days. However, eventually, I got this problem where every time I changed the volume or brightness the system would get really weird (the slider wouldn't show up and the icons on the taskbar wouldn't work anymore for about 10 seconds). I called Dell and did a fresh install of Windows with them, and the problem was gone for a couple of days. However, today I did some updates inside of the Dell Update app (including a BIOS update), and the problem is back again! Is anyone else facing the same problem and/or know how to solve it? Been bugging me a lot.
