Brave appearance in ubuntu

Description of the issue:
I installed latest version of Brave 1.78.102 on my latest ubuntu 25.04, the appearance of the textbar or the whole browser is very weird, I’m also using firefox side by side so when i switch to Brave It feels primitve due to the appearance, this is not snap but .deb version. I had uninstalled snap version then installed it directly from site and terminal, I’ve also turned on the option of ‘Same as Linux’ in appearance bar, tweaks are installed, graphics are fine in other browsers but not on Brave, I’ve used brave from long time in android and I hopt there’s a solution
Steps to Reproduce (add as many as necessary): 1. 2. 3.
Install Ubuntu
Install Brave from terminal though the code on main webside for Brave Linux version
curl -fsS https://dl.brave.com/install.sh | sh
open Brave
