My workflow has always been to export artboards (typically of the latest iPhone) @3-5x, and drop them into a keynote presentation. Obviously this often involves several dozen artboards at the very least.
For several releases now, every ~7-8 images I export is completely ruined by strange artifacts of the export. This totally ruins my flow when I drop the file into my keynote and realize I have to go back, find that exact artboard, re-export, find it again in finder, and drop in.
I know my colleagues are experiencing the same thing. This is basic, table-stakes stuff and I’m sorry, but it’s genuinely shocking this bug has persisted so long.
Hopefully this is something you’re aware of and a fix is in the pipeline?
