I am having a very serious issue. I just updated to the latest Ubuntu version (the old one was Ubuntu 20.04.1 and the new one is 20.04.2), and I didn't restart my PC. I started a video clip and noticed that the display looked awful, like big pixels everywhere. I decided to restart my PC and now after the Ubuntu logo on boot it looks like in the picture below.
Please, anyone, know how to help me?
