Qt apps under Wayland display Adwaita CSD on Gnome 42

EDIT: See next post. I misunderstood the issue.

***

Hello. When I run a Qt app installed via Wayland, the CSD displayed under GNOME Shell is an Adwaita titlebar. I'm using an alternative theme though.

Under Plasma this worked fine. But of course, Qt apps in Plasma were handled by Aurorae instead.

I've added an override to expose the ~/.config/Kvantum and ~/.themes folders for all apps, like this:

flatpak --user override --filesystem=home/.themes:ro

, that works on Plasma but under GNOME Shell, no dice.

Here is my .zprofile:

export QT_STYLE_OVERRIDE=kvantum

### IBus
export GTK_IM_MODULE=ibus
export XMODIFIERS=@im=ibus
export QT_IM_MODULE=ibus
### IBus (netns workaround)
export IBUS_USE_PORTAL=1

export PATH=$HOME/.local/bin:$PATH
export XDG_DATA_DIRS=$HOME/.local/share/applications:$XDG_DATA_DIRS

Any hints here? I can't seem to find any info on this so I feel like I did something very wrong somewhere. The wiki explains how to make titlebars fit in using Adwaita, but I'm trying to use the Colloid theme. Colloid is installed on ~/.themes and ~/.config/Kvantum already.

Re: Qt apps under Wayland display Adwaita CSD on Gnome 42

I just realized this happens to all QT apps running with QT_QPA_PLATFORM=wayland.

This is even worse. Is this normal? Do I have to run all apps under XWayland? That would be sad.
