The enormous top bar I'm talking about
This bar appears whenever I use an app such as eclipse, visual studio code etc etc, and I don't want it to be there because it confiscates a bunch of the area I'm supposed to see. I tried hiding it through the app but there is no such option. I am pretty sure this is ubuntu-related (and it might just be displaying the title).
If there is an option to make it smaller (at least) I could also use that. Sorry if this is a bad question, I'm quite new to Ubuntu (as you might've noticed already) and this forum.
My Ubuntu version is 22.10 if that makes a difference.
