2D Games graphic problem (Linear + XBR = On)

[LunaMoo]

Dunno about your definition of "better":P. IMHO clear graphics is far better than having glitches all over the place.

Anyway if texture scaling does not hide such issue completely(usually a minimum which does that is x3+) then you are stuck with x1 res or glitches, choice is yours.
Probably best way to improve 1x res further in such fully 2D games would be by some full screen upscaling shader, but there might be something wrong with those, or at least I couldn't write one which gives expected result in ppsspp and gave up on them;3.
