I'm getting weird colours and lines on my photos

Yes, it is Lightroom - sorry! I didn't understand the question, I thought it was a Lightroom forum. Yes, it seems like the GPU as my laptop sounded like it was about to lift off with all the noise and processing. Thank you for the reqiurement links! 

I'm assuming this is Photoshop.  But it could be PS Elements, Lightroom, Lightroom classic, Bridge, Adobe Camera Raw, etc...

Which Adobe App are you using so a moderator can move this topic to the appropriate product forum for you?

Does it print that way, too?

This looks like a problem with your GPU (graphics processor). 

Make sure your computer & GPU meet the minimum requirements.

Also ensure you have the latest graphics drivers for your video card. It's best to download them from the card maker's website.

Hope that helps.

with what adobe app or adobe service do you want help?

Okay, thank you. It's my first post here so still learning 🙂 

In the Mac Desktop 

what app?

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
