How to get rid of white line border?

[seasurfer]

Since upgraded to Mac OS 26, I realized that everything has a thin line white border around the edge, even when you play a game like World of Warcraft, there is that thin line white border.

Yes, I have tried turning off "increase contrast" in Accessibility and I still see that white line border everywhere.

Try clicking “Only in Stage Manager on click” in this setting:

I don't have white line borders, but I'd like to help. Can you post a screenshot?

Did you try the setting I suggested?

Is it these white lines?


If so go to System Settings > Accessibility and toggle OFF the Increase Contrast:



If it's not those, then - as suggested above - maybe post a screenshot?
