Yesterday, my Macbook pro 13 screen was starting to look weird. As you can see on the picture, there is black "stage light" from the bottom of the screen, which is very annoying to look at. Especially on white screen. Thank you in advance.

Hello and welcome to Apple Support Communities, mille30.
If I understand your post correctly, there are bright and dark spot at the bottom of your MacBook Pro display. I'd like to help.
First, try this reset:
Reset NVRAM or PRAM on your Mac
If this issue continues, let's do some testing to narrow down the issue.
Safe mode will tell us if the issue is related to a startup item or plugins, and sometimes corrects the issue. This article will tell you how: Use safe mode to isolate issues with your Mac
If everything is working correctly in safe mode, but is not working when you get back to your user account, please check the section titled "If an issue doesn't happen in safe mode" for the next troubleshooting steps.
If the issue continues while in safe mode, a test user will let us know if the issue is isolated to your account, or system wide: How to test an issue in another user account on your Mac. If the issue happens in the test user also, then please check the section titled "If an issue happens in more than one user account."
If the issue continues, let us know the results of each of these tests.
Thanks for using the Apple Support Communities. Take care.
