Priority Tiles blurry when not using the default resolution

[Takashishiful]

So I changed my game's resolution and used Multitweaks to give the game a pixel art style. But it seems that tiles put through Cyclone's Tile Priority gets blurred, while normal tiles aren't. (because of Multitweaks) I was wondering if there could be a way to give the tiles no blurring/anti-aliasing effect when a game is a lower resolution scaled up.

Example: What I have (left) and what I'm trying to get (right)
