How do I disable dither on PNG export?

I am running Ubuntu 18.04 and have Gimp 2.8.22, however I can install a newer gimp if that is what is required.
Also it has occurred to me that Mirage and Occular may not be Scaling it up correctly, which results in the appearance of dither. I am not sure how to verify this.
If I open that same .png file in gimp and zoom in, then it appears correctly.
If this is just Mirage doing bad scaling on zoom in, does anyone know of another image viewer that could be used? (something lightweight for quickly viewing an image, no editing.)

Appreciate any help

here is the png I exported from gimp (to look at this I don't really see dither, but 16x16 is really small):

here is a screenshot from within gimp:

here is the exported PNG opened in Mirage (notice the dither?):

Gimp exports to PNG pixel for pixel.

Then it is not dithering, it is blurriness. It depends on the interpolation algorithm used for scaling. In an editor such as Gimp you want to see pixels when you zoom in so the zoom does not interpolate, but other image viewers can make other choices.

Here is how your image appears in my image viewer (Gwenview):

excellent! I was wondering if it might have been something like that. I have remove mirage and installed gwenview, thanks!
