Hey everyone,

thanks for the help.
After some searching I found out that the support for my graphics card 
was added into nouveau in this kernel version and therefore these 
problems did not occur before.
As my laptop is a hybrid laptop and can either use Intel or Nvidia 
graphics, I fixed it by blacklisting nouveau.

Thanks to everyone for the help.
