[Linux Wayland] Window borders not appearing on GNOME desktop

[Yona-TYT]

Using: Fedora Linux 43 (Rawhide Prerelease) GNOME 48 in Wayland
Currently, Simutras runs directly on Wayland (not XWayland).

This issue with the Simutras window has been present for a while. It's related to the move to Wayland on GTK desktops. I've been using QT desktops, so I hadn't noticed this still exists on GNOME.

Could you check if this happens with other SDL apps? (OpenTTD maybe?).

I tried running openttd , but it doesn't work natively on wayland, I tried using "openttd SDL_VIDEODRIVER=wayland" but this didn't work for me.
I tried wesnoth, and it does work natively on Wayland, and the borders/window decorations work correctly. However, wesnoth uses "SDL2_mixer".

It could be that this is an issue with SDL3 (which just uses a wrapper to SDL2 to compile on some Linuxes). Is it steam or the nightly? SLD2_mixer is still old plain SDL2.

This is one night..

Maybe try self-compile.

You're right, compiled Simutrans doesn't have any issues with window decorations.

However, I'm concerned that regular users might have this problem when running Simutrans, most don't even know how to compile their own versions.

Usually, Simutrans comes with the respective distributions ...

Which version of SDL did you compile with?

Well, there is the reason I created the Simutrans flatpak.

This looks like the Fedora package depends on SDL2 without libdecor support. Do you have multiple versions of SDL2 installed? (Or maybe wesnoth statically links to the libdecor-enabled version?)

In Fedora, it should be the "SDL2-devel" package, but in the version I'm using, when I search for it in the package manager, it appears as "sdl2-compat-devel-2.32.56-1.fc43.x86_64". I always compile using the libraries included in the official repositories

This looks like the Fedora package depends on SDL2 without libdecor support.

Is libdecor only for GTK windows? Or is it also used in QT? On the lxqt desktop, decorations work fine in Wayland.

The compat-level SDL2 is actually an SDL3 ...
