Something about the corner on the screen

[x-leehe]

Hey guys I'm using Arch Linux with hyprland(with Illogical Impulse configuration) now and I've using it for more than roughly 3 months. It's working well, smooth and efficient. However there's still something disrupted me: How can I turn off the rounded corner on the screen? I've been searching in the configuration files for some time but still have no answer.😥

But still a nice job. Despite some fcitx5 issues(that's hyprland's problem), it is really a great job, which amazed my friends.
