Today I got an update and graphics are not working right on Ubuntu 16.04

today I got an update and system graphics started performing in a very poor way, they're laggy and not as fluent as they were before.

As additional information in this same system, I tried Ubuntu 18.04 and got back to 16.04 as I had the same issue.

Here is the last update i got:

I think it may be related to the kernel being updated but I don't have a clue on why suddenly the graphics became laggy.

I'm running an Intel Core i7-8550u with no external GPU.
