I'm afraid I'll always answer such questions like this, but here it goes...

It looks like a graphics issue. Do you have any GPUs in your machine? If so, using the proprietary driver may bring up such problems sometimes as you update your kernel version. That happens a lot to me, and I still don't know how to fix it. Although I always install the Nvidia proprietary driver with dkms, the driver always fails to mount onto the new kernel. So, in a nutshell, if you do happen to have a GPU and its driver installed, try reinstalling it and then booting the new kernel again.

Hope it helps!
