When I saved my file in .png I get weird lines on the artwork I'm working on (when previewing my file):
Oddly enough, I don't see them at all on my .ai file. Everything looked fine but if I ever wanted to save it in .png, or .jpeg it's not the same. And I can still see some lines on my wallpaper, when uploading it on my personal drive.
Does anyone have this problem? If so, how can you fix it? I never had this problem until now and it's very unusual. I have done some research on how to fix this kind of problem but so far I have not found many. I have also tried other methods like saving it in different formats but not much difference to me.
I would appreciate your help, thank you for reading!
