I use a small notebook so it comes in handy to double the title bar to have space to increase the title font to 16 or 18
On debian 12.11 this was the case, but I don’t remember how I configured it or what style I used. The style I now use on debian 13 is adwaita
I don’t get it then. I installed debian 13 with xfce and now I’m using gnome??
No you ommited any kind of detail in your original post so we all had to guess to try and help. You’re still using xfce if that’s what you chose on installation. Pro tip install fastfetch open a terminal and write fastfetch and post the results under your future posts it’ll give us a report of your system.
