Transparent background showing black

[Eva26933011qhry]

Hi there,

Today, when opening a new file or opening an old png file with transparent background, it's showing up with a black or grey background. When I hover over it sometimes flickers into a transparent background.

How can I fix this? I'm on a mac and have restarted PS but nothing has changed.

 

 

thanks so much!

Hi

Try enabling this option in preferences and restarting Photoshop to see if it helps

Alternatively, try restoring your preferences using this manual method:

If that doesn't solve it, you can quit Photoshop and put the Settings folder back
