Exporting to pdf or exporting single page to png broken

i use penpot to make a big project (50+ full image pages). sometimes i need to export all pages into pdf, sometimes i only need 1 pages to export to png

sadly i have to retry exporting a single page 4-7 times just to make sure all image rendered. why is this happening? i’d rather penpot process my request slowly than broken images everywhere

and dont get me started when i try to export a single project (with 50+ pages) into single pdf… 10% of the images broken. the export is not that long, but i dont want to each pages for broken image, and then re-export and yet still no guarantee all the image will be rendered.

is there a way to make export takes longer time but guarantee no issue?
