I use a screenpack with localcoord 384,224 with mugen.cfg and system.def on this same config, the chars too.

only the stages i set them on 420,240, it enables to my chars to increase the size a few more, but the stages looks perfect if my chars are stopped,
when i move the camera the stages make a horizontal distortion. (kinda an acryllic effect)

in case of animations that use vertical moves the issue occurs too.

how to fix it without set the stages on the same config?

obs: all the stuff is low-res
