Pixel Preview Bug?

It seems like Figma is telling me my icons are off the pixel grid. I’m pretty certain that they’re on the grid however.

It seems like when I ‘refresh’ by toggling pixel preview it fixes the issue. But then when I zoom out or move around the canvas they become blurry / appear off the pixel grid again.

One caveat is that I had imported icons over from sketch.

That definitely looks like some kind of a bug. Does it happen if you set zoom to rounded numbers like 1000% instead of 929%? Can you share the file?

I can but can I do it privately?
