Keyboard problem XPS 15

Dear community,

I have a XPS 15 9560. I really love this thing! But since a few days (maybe since a few updates I ran?) my keyboard started lagging. It skips some letters of numbers randomly. They all work individually though.

I already tried a few things, but nothing worked yet. While searching, I found that my keyboard has 2 drivers. So maybe that's a problem?
