Hi guys

Recently upgraded one of my employee's hardware to a new Macbook Air 2020 which is on macOs 10.15.4 (Catalina)

Using Pixelmator Pro 1.6.3, we often see noticable graphic artifact whenever moving a layer over a coloured background.

Those are definitly artifacts as it's not in exported files.

I noticed that if I hit "reset transparancy" in settings, those lines disapear.

I can't reproduce it with my Macbook Pro 2017 though...

Any advices?

Hi there, it looks like you tried sharing a screenshot with us but it looks like the upload might have failed — any chance you could share it again? Also, if there's a particular file this happens with, it would be great if you could share that too! You can upload it to then copy the link you get and paste it here. Or, if it's a file you'd rather not share publicly, feel free to send the link to

Thanks a lot for all those details, I've passed this on to the devs and we'll see if we can reproduce it on a similar device!
