Zoom artifacts in avisynth preview window.

[kingcrimsonster]

When I press "avisynth preview", is opening a window with the size equal to the screen size my monitor. There is a poor-quality image zooming. I can not properly adjust the filters for sharpness, deblocker, noise etc.

This sample screen from file, that saved from avisynth preview window - "save image".


Please set the zoom function in the preview window with option 1.00 zoom, similarly zoom function in the vapoursynth preview window. This is a very necessary function.
