And here's a weird one

using a .jpg import, nothing out of the ordinary … . .

Try importing the image into Inkscape and saving as an SVG file.

I have seen that when you go over the top in memory. particularly in an engrave. You might try a PNG that is more memory up front but perhaps less when swelled out. If you also do an increased contrast it could look better as well Jpg makes a mess that way/

Hello @Deleted I’d like to gather some additional information in order to best assist.

Are you getting the same message on any other designs or files?

Have you tried to use another browser? If so, are the results the same?

Can provide a copy of the file you are using? Once I have your file can attempt to recreate the issue during my investigation.
