GTK titlebar not showing anymore

[claymorwan]

The gtk titlebar suddenly decided to not show up anymore, instead showing the system one. It's weird knowing that I haven't disabled it:
Here's how it's looking rn, using the system titlebar instead of the gtk one

custom-shader = /home/claymorwan/Priv-dotfiles/submodules/ghostty-shaders/m-ahdal/gears-and-belts.glsl
clipboard-read = allow
theme = catppuccin-mocha
cursor-style = bar
font-family = JetBrainsMono Nerd Font
gtk-tabs-location = bottom

I also try to enable it in the config by doing gtk-titlebar = true but it didn't work

Distro : Arch Linux x86_64
Kernel : Linux 6.12.10-arch1-1
DE : KDE Plasma 6.2.5

I may be stupid
tho pretty weird it suddenly stopped working like that

It's a documented change in how window-decoration works. It now defaults to auto which switches to server-side decorations on Wayland/Plasma.
