This has nothing to do with texture filtering, you're using cached texture scaling which requires stable textures for performance reasons and will not work on unstable/changing textures.

Disable texture scaling, if you really need it, use real time scaling(not available in official builds, it's also more demanding and applied every single frame which makes it lag fest if normal scaling causes at least a stutter), but I don't recommend using any form of texture scaling for tile based games like this as it causes artifacts - you can see them clearly for example on hp bars, but it's also within characters textures and other graphics, texture scaling will never work without glitches in games using tilesets for textures, it's just not possible with any algorithm in existence.

Either way you have only two choices for acceptable graphics:
- not using any scaling at all,
- using full screen scaling via post process shader like 5xBR(would be same, but it can't be same since this isn't PSP native game and resolution of texture to display would have to be 1:1 for ideal post process scaling).
