This problem is supposed to be fixed in XnView MP 0.98.1. Please check and confirm the bug fix here.
My system is Windows 10 version 20H2, scaling is 125%, image samples below:
Original image
XnView Classic 2.49.5
XnView MP 0.98.1
XnView MP 0.98.1 (with "Zoom on HiDPI screen" off)
I can confirm that when viewed at 1:1, pixel art is obviously scaled with nearest neighbor with "Zoom on HiDPI screen" turned on, and with a Resizer with "Zoom on HiDPI screen" off, despite that you would expect in the latter case that it never goes through a resizer at all. Even with High Zoom Quality set to never. I can only guess, but it seems like it's being upscaled and then downscaled back to the actual pixel size, instead of skipping the step entirely. Maybe the two cases were flipped somewhere in the code?
It's also obviously using bilinear to downscale even when High Zoom Quality is set to never, which I suppose is a separate but related bug.
I have to select bilinear in quality scale settings. All other settings result in bad nearest neighbour image down scaling. Or if none selected its normal nearest neighbour image down scaling. Which isn't nice.
But if bilinear in quality scale settings is selected, all images are scaled. Also those which don't have to be scaled as small enough to fit on screen. Als long as I press my left mouse button, the picture is correct again.
Where can I get older versions as this annoys me a lot?

XnView MP 0.98.2 is still more blurry than XnView Classic 2.49.5 .
It seems that small images rendered similar, but big images are still blurry.
I can't reproduce, what do you have in 'High zoom quality'?

why 'bad nearest neighbour image down scaling'?

Thanks to your detailed description I can reproduce
