Short description of error
Hello, When I opened Blender it had a different title bar after talking about it on, #blender-coders on blender.chat (https://blender.chat/channel/blender-coders?msg=Tzh3fZCg2HgEdkXZa), I have to use WITH_GHOST_WAYLAND=OFF, and it only happens in Wayland.
Exact steps for others to reproduce the error
Just open Blender 3.5.1 on Wayland

Quoting @deadpin from chat:

From https://code.blender.org/2022/10/wayland-support-on-linux/
"Gnome-shell has decided not to support server side decorations, meaning it’s up to each application to define it’s own window frame (title bar & window borders). For developers of tool-kits such as GTK/QT, this makes some sense as they can build window drawing into their toolkit. For a cross-platform applications like as Blender it isn’t so convenient, although longer term we might look into client-side decorations. For now we’re using libdecor and we’ll see how it evolves."

@ideasman42 : that sounds like this should/could be closed, right?

I wonder if this is related though: https://gitlab.gnome.org/jadahl/libdecor/-/merge_requests/43
Looks like it might be possible to fake Gnome-looking decorations now?

The current version of libdecor (1.1) doesn't include the GTK theme.
When the next version of libdecor is released it will contain the updated GTK theme (which looks like it uses gnome/GTK native title-bars), however there is currently a library conflict, see:
https://gitlab.freedesktop.org/libdecor/libdecor/-/issues/47

To test, build libdecor (without installing) and from the libdecor checkout run:

bash -c "env LIBDECOR_PLUGIN_DIR=$PWD/build/src/plugins/gtk LD_LIBRARY_PATH=$PWD/build/src blender"

Prints:

Plugin "GTK3 plugin" uses conflicting symbol "png_free".
No plugins found, falling back on no decorations

While the demo works:

 bash -c "env LIBDECOR_PLUGIN_DIR=$PWD/build/src/plugins/gtk LD_LIBRARY_PATH=$PWD/build/src ./build/demo/libdecor-c++-demo"

Closing since this will be supported when libdecor is updated, although the library conflict will need to be resolved too, from what I can see this is an issue for libdecor to handle.
