Wave Warp Low Rez

The Wave Warp plugin breaks down when larger sine waves are used - it almost appears to use a raster map to distort an image instead of procedural math.   Been like this for several decades, finally getting around to asking for it to be fixed. 

Doesn’t matter what bit depth the project is in - this happens with 8, 16 bit etc.. at Best layer quality (though it looks like Draft, doesn’t it?)  And antialiasing in the effect is already at High.   View below is actually zoomed out, not in despite how pixellated / chunky it looks.
