title: PySide6 only uses system theme on Macbook, not Linux
body: <p>I'm making a program in PySide6. Testing it on Macbook the project uses the Mac's dark-theme, but running on Arch Linux it's running the default &quot;Fusion&quot; theme even though I have set the QT6 system theme <a href="https://wiki.archlinux.org/title/Uniform_look_for_Qt_and_GTK_applications#QGtkStyle" rel="nofollow noreferrer">like described on the wiki</a> with <a href="https://archlinux.org/packages/community/x86_64/qt6ct/" rel="nofollow noreferrer">qt6ct</a>. The theme works on the qt6ct program itself, is there something I can do in the project, or on my system to get the system theme in my project?</p>
