I am working on a simple folder Icon. Everything is completely aligned to the pixel grid. See this example image:

But when I go to the menu and select “Pixel Preview” to preview how the icon will look at 100%:

The resulting image and UI components in my file look distorted, some with double borders, etc. It just looks janky:

The interface zoom is set to 100%. All shapes are aligned perfectly to the pixel grid.
I noticed that if I set the interface scale to 80%, everything looks crisp. See this image:

But I can’t work like this. The UI is way too small. Why does pixel preview look horrible for me when the interface is at the default 100% scale?
Possibly Related: I have a 4k monitor and my Windows DPI scaling is set to 125%. Could this be causing the issue?
Can someone help?
Edit: I don’t know why, but the last image with the UI scaling set to 80% looks a lot larger in my browser than it does on my desktop. The UI controls are super small despite this image looking like they aren’t.
Either way, the pixel preview should not be distorted when my UI scaling is set to 100%. Just wanted to add that caveat.
