Fullscreen Apps?

[dvvdv]

How can I force an app to be fullscreen?
Here's my problem:

As you can see, the app doesn't go fullscreen, and the dock is still showing!
Any way to fix this or make the app go fullscreen? Any advice would be great!

What happens when you click the green maximize circle (beside the red close and yellow minimise)? Should make the app fullscreen.

Strange. That app (and others) go full screen for me with that button.

Maybe try updating the app?

Edit: oops I thought you were using just Transmission.

The update option still holds. If the app is massively out of date then it might not be asking the computer correctly for full screen. You should be on 5.15.4.
