AppImage, Flatpak to test window centring

[mcarans]

Please can you test this appimage:

I took an appimage and replaced various files with ones from nix to give the same SDL version as the Flatpak.

Newer appimage and flatpak to test:

Both have a separate SDL2 executable (source here that shows the splash screen that is launched by the startup script before Oolite is launched. The AppImage although built on Ubuntu 22.04 has newer SDL (while retaining dependency on old glibc) copied into it - it uses the same version of sdl12compat as the Flatpak and calls through to SDL3 via sdl2compat.

EDIT: the appimage and flatpak here also have a no network fix: https://github.com/mcarans/oolite/actio ... 2839998737 but this AppImage does not have upgraded SDL.

I tested both the flatpak as well as the appimage on Ubuntu 24 LTS, running them several times.
The startup screen looks centered on my primary display. After that the window comes up maximized.

While the flatpak showed the game window on the primary display all the time, the appimage shifted the main window to another screen - but only starting from second attempt.
Regardless the location, the splash screen is centered now and the application window seems to remember where it belongs.

That's great news! Thanks for testing.

I have raised an issue in the GNUstep base repo for the no network issue so hopefully the Linux-specific workaround can be removed in future.
