Hello there fellas, my Slot1 suddenly developed a strange bug, where some of the backgrounds and sprites are looking weird.

Here is a YouTube screen capture: https://youtu.be/UNV9CKkASFk

Firstly I thought its just a dirty card, but after reseeding the card multiple times and also testing with other cards its still the same. I've tried cleaning also the slots and reseeding the mini board that connects the cartridge to the main board, but the issue still persists.
Any help and directions to fix my board will be greatly appreciated.
