Zooming out makes the image blury

[CommanderMark4]

idk if this is new, but it looks like zooming out aply a "anti aliasing" effect to the screen and makes a normal "zoom out to see your work" a nightmare (it becames blury)... I don't remember having this problem before.

[my wife left me for a pear]

That's probably due to an option available (and enabled by default iirc) in Preferences. To disable it, go to Edit > Preferences > Experimental, and uncheck "New render engine for sprite editor". After pressing "Apply" it should remove all the blur when zooming out.

It didn't, but changing the scaling did the trick (screen scaling 100% and UI 200%... I never changed those options before I think).
I found the aswer here: https://steamcommunity.com/app/431730/discussions/0/1741103267279077227/

In fact after changing the scaling and going to preferences > editor >downsampling and selecting biliniar mipmapping made it better as well.

then the original is not saved,but it is scaled and modified every time you zoom.
it loses quality if you do not use the saved file,but the current file.
in my own python project i use a reserved image,and every time it scales.
i use the reserved image,not the current image.
so basic this is a programming problem.
where it scales the current image over and over again,instead of using a reserved full quality image.
scale'ing always effects the quality,even if you use a reserve image.
that just happen when you let the computer draw/scale your image.
the amount of pixels changes,thus it effects the quality.
a reserved image resets it every time,but in the end the drawing is modified.
its scaled.
this effect is clearly visable if you modify your image from like 32x32 to 128x128.
some line will be too thick other lines too thin....
a loss in quality.
only the original is pixel perfect.

let say i have 10 pixels, 5 red 5 blue,divide by 2 is no problem.
but now i scale to 11 pixels.
should it become blue or red? ( now we have a problem)
scale to 12 no more problems.
see how quality is lost.
we can end up with a remainder.
letting the computer modify/zoom/scale your file,will thus always effect the original.
