[0.17.9] Mipmap causing blurry graphics

[HLPL4Y3R]

Mipmap is causing lower tiles to become blurry, especially in low vram devices
Also is worth mentioning that the same is happening with Linear Filtering for icons

(Yes, i'm using a custom driver graphics, i tried the original drivers and the problem persisted,
Also the settings are the same from 0.16, however i did not used mipmap and linear filtering)

Thanks for the report: the zoomed-to-world view uses a slight blur filter over the entire screen.
