I didn't test but I am sure there are no differences between ocs/ecs/aga. It is just a side-effect of how sprite DMA fetches are done, single sprite line needs two separate fetches and sprite can be loaded to output shift register even if its data has not been fully loaded (or even not loaded at all)

I think it should be quite easy to work around it by having multiple sprites (one normal, one that has second plane shifted by one pixel vertically and so on) and selecting correct depending on sprite's x-coordinate.
