Increasing interal resolution for Ar tonelico without getting graphical glitch?

[stormofdarkness]

It is possible to increase the D3D resolution w/o getting graphical glitches?

I have tried to increase the resolution in a "multiplier fashion" but it didn't help at all(ie: native is 640 x 448 and I would increase it to 1280 x 896, which is multipied by 2). Interestingly it runs fine at 640 x 512...

I am using the latest Gsdx, r1763.

Thanks in advance

Upscaling isn't perfect and has this issue in many games.

depends of the game, for exemple some like 1080*1080.
