Bugged display and very slow

Hi, I hope anyone could help me here. Did the install of Sequioa 15.7.1 on my MacBook Pro Late 2013, 1TB SSD, 16Gb RAM, one month ago.

Yesterday the display bugged as you can see (no background image and that white line around the apps logos, the dots are dust ahah), and the computer got very slow.

I checked the root patches and I post what it says

Really hope someone can help me because I really need the computer.
