Problem is with nouveau. The nouveau driver for the Nvidia Maxwell
cards is rudimentary and unstable.
Reporting these problems will not help (NVIDIA is the bottleneck).
If you want to try something that might enable you to use the Nvidia graphics
you could try “Bumblebee + the official Nvidia drivers’. I have no idea if 
this will work with your hardware.
Or the official Nvidia driver and Optimus/PRIME (if that works).
Personally I would not go to all that trouble and stick with the Intel graphics
till something changes for the better.
