Launch BambuStudio

Actual results

It has 2 titlebars, the window manager one, and the application provided one.

Expected results

Just one titlebar.

I've managed to hack this changing the value of BORDERLESS_FRAME_STYLE in src/slic3r/GUI/MainFrame.cpp to (wxRESIZE_BORDER | wxBORDER_SIMPLE) but that makes the minimise and maximise buttons not work (the minimise button shouldn't appear on my GNOME system), and the window isn't resizable

Windows has done special processing. But we don't have much energy to optimize Linux version.

This happens not only on the flatpak version but also on the built from source version: Orca Slicer inherits that too, unfortunately.
