Different scales (or resolutions) for different apps in the same screen? Today my cat stepped on my keyboard and somehow changed the scale of one app. The problem is that scale of the display is globally the same what changed was the overall resolution of my app.



In the image above, there's the corner of chrome in the usual resolution, on the right is the corner for Discord, much much scaled.

I also added a photo of a widget within Chrome scaled.
Anyone knows how can I correct this?
Thank you in advance.
If I am understanding you correctly one app seems larger than another app?

Unfortunately it is not possible to adjust the resolution for an individual app. On macOS (and Windows too) the resolution of the screen is set on a screen by screen basis and can't be set for a specific app.

In System preferences > Displays

You can adjust those parameters.

If you have more than one display you could adjust the resolution on each display and keep those particular apps on the screen they look best on.
