Album Art Has Low Quality

[Chonga2520]

The album art shows in a low quality. It was very noticeable when I loaded Moe Shop (w MYLK) - Magic. There were jagged lines. I also tried it with some other songs and album arts, it was also lower quality than the original pictures I have. The issue seems to be the same with jpg and png files too.

Here are some screenshots, and also the original album arts:
