I have created a design in Kicad (5.1.6 on Mac) and while looking at the Gerber preview in JLCPCB I noticed a the corners of the small pads look distorted.
Has anyone seen this before?
And any suggestions how to address / review this?
An earlier design file preview in JLCPCB still works and renders OK. But I have no idea what I am doing different.
JLCPCB viewer is known to be buggy.

Thanks! I searched using the wrong keywords…
Then I’ll assume it is just the viewer and in production it will be OK.

Nothing to do from your side, this is an online gerbiewer bug, I have seen this today also. You should inspect your gerbers via kicad internal “gerbview.exe”, and also, another online fabs have other viewers, seeedstudio has it. Hint: gerbview.exe from development nightly branch is much better than one from kicad v5.1 branch.
the preview, as noted from other, are buggy… yesterday I received my boards and are fine!
Yes, but the bugs appears to be random. I uploaded a different design with the same pads that I had exported from Kicad earlier and that rendered fine.
I also contacted JLCPCB and they confirmed my input is OK (which I concluded myself too by using the Kicad Gerber viewer). They have forwarded the visualisation bug of the Gerber viewer to their IT department.
I noticed this too - my boards are on the slow but cheap shipping method so good to hear it’s not a problem with the Gerbers.
