Artifacts when zooming .PNG files with transparent background in MP version

When I view .PNG files with transparent backgrounds, if the zoom is set to 100%, then they display properly with no issue. For example any kind of logo file.
However if I zoom them either up or down by any amount, they are full of weird artifacts.
XnView Classic does not have this problem, it displays the images perfectly without any artifacts no matter what the zoom level is. Just the MP version has this issue. And it's had it forever, since years way back and is still there in the current version.
Could you please fix this so the .PNG's display properly at any zoom level?
Thx

But it's not just that particular logo, it's every one...
Here's another...

Not sure what that cryptic reply means?
Can you be more clear and answer with one of the following?
1) This is a known issue and is going to be fixed
1B) When? Given that XnView standard doesn't do this should be an easy fix?
2) This is a known issue but is not going to be fixed
2B) Why? Outside of the capability of the software? Or what reason?
3) This not an issue, it is operating as intended
3B) Why would it be intended to do that?
Thanks

Until it's fixed:
Tools>Settings>View
Use checkerboard pattern as background > (enabled)
High Zoom Quality > Make sure "Zoom In" and "Zoom Out" both show "None"
Back in the main Screen, go to View under the title bar. You may have to toggle "Use Alpha Channel" on or off.
