Small pad conners distored at JLCPCB Gerber viewer

JLCPCB viewer is known to be buggy.

Why does SMT 0805 footprint look strange in JLC gerber preview?

I’m working on my first board with Kicad, and have it ready to submit to JLC for fab. In the JLC Gerber viewer, the pads on R1, R2, R3 look odd - it’s like the solder mask is extending into the pad area? [image] In pcbnew, it looks like this [image] It also looks OK in the Kicad gerber viewer: [image] I generated the Gerber and Drill files according to the instructions on JLC.

JLCPCB gerber preview issue

Interestingly the other JLCPCB preview is fine: [grafik] and the website states: The gerber viewer is for reference purpose only and may differ from the actual PCB product. So I would assume that this is just a preview issue.
