Exported PNGs full of ugly artifacts; intermittent image errors

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?

Hi @homer :wave:

Welcome to our community! Thank you for your report. Would you be able to share a sample document that we could use for testing? This would be helpful in further investigating the situation.

If you agree, please send the sample file to productsupport@sketch.com

Cheers :pray:

Hi @Cris. Unfortunately I’m not able to share my file for confidentiality. There’s nothing unusual about it though; liberal use of blurs, & layer effects, as one would expect in today’s design landscape.
