I tried to export a PDF - ready to be sent off to my print shop... I was lucky to have really, really carefully inspected the produced PDF, because it was full of errors. It looks like Affinity Designer 1.8.1 (App Store version) I can't really be trusted anymore. The file looks fine, but exporting or printing on my local laser printer is now often not reliable and produces strange glitches.
Not sure if this is related to the boolean operations bug - but it looks related to me...
I have attached a reduced file to show you the error
looks fine in Affinity
print dialog already shows glitches
pdf opened in PDF viewing app with glitches
Affinity file with problems
