I’m not sure if this place is a good place to ask for help, If it’s not, simply delete it, and sorry.
I’m trying to help bring dune dynasty project (a reverse enginering project of dune 2 game) to flatpak, we get the project compile and run fine, but when we exit the game, it doesn’t work. The person maintaining it, seems to have it working with the linux subsystem for windows with ubuntu, in X11, but with Fedora & Wayland doesn’t seem to stop, I need to run a kill command or similar to get it to stop. (Black window/full-screen is always there)
Right, I did assume you have Wayland support for my previous comment…
My bad.
Anyway, if you used the same Flatpak on both Steam Deck and your other System, it doesn’t sound to me like its an issue with Flatpak itself.
Maybe related to some GNOME Shell extension or hardware/software correlation?
I can confirm the same issue (on closing the software a black screen window remains). Using gnome on nix os and using the flatpak version of dune dynasty on a Thinkpad T14 gen 2.
nothing that I added myself, but the Nix OS Gnome Desktop image likely has some pre-installed, I’d have to do some digging. Per gnome extensions app “no installed extensions” The OS install is was only a few days old when I installed Dune Dynasty, so there really wasn’t that much different from a stock install, basically just installed flatpak, gedit, steam, git, and cmake. Nothing that seems like it should affect the desktop environment.
