Photos appearing pixelated

Hi,

Hoping someone can help with this... or can Apple please explain why this is a problem and when are they likely to resolve it.

My iPhotos library transferred successfully to the new Photos app... and I have also imported brand new photo's from my camera into Photos app.

Every single photo appears blurred and not the sharp image I expect from my SLR. When I zoom in on a photo, it appears pixelated at first and then corrects itself. I then zoom out and the photo appears as it should and no longer blurry\pixelated. If I close the application and go back to the photos i've just looked at... the problem reoccurs and i'm having to zoom in and out again.

I review loads of photos regularly and delete rubbish ones... and having to zoom in and out for the image to appear properly is really frustrating.

Has anyone experienced this problem and do you have a fix for it ?

... and does anyone else find the name of this new app annoying as well ?? Trying to search for fixes online when the name is simply 'Photos', makes it difficult to find what you're looking for 😟

** I have a macbook pro and everything else works as it should and fast with no issues.
