Have you identified any steps to reproduce the bug? If so, please describe them below in as much detail as possible. Use images if possible.

Yes. Set the shell variable SDL_VIDEODRIVER to wayland so that SDL uses a Wayland backend. The game window will not appear, but audio will play in the background and no errors will appear in the terminal, signifying that the game has not crashed.

Please describe your issue. Provide extensive detail and images if possible.

When SDL_VIDEODRIVER is set to wayland, programs should run normally without any additional modifications. I'm not exactly sure if this is an issue with HaxeFlixel or Lime more than it is an issue with the game. It may be a Lime issue based on the fact that it has its own version of SDL. I did rebuild Lime via lime rebuild linux -64 -release, so using a pre-built version of Lime is not the issue.

To mitigate this issue, one can set SDL_VIDEODRIVER to x11, which is currently the default, but relies on XWayland.

If you're game is FROZEN and you're playing a web version, press F12 to open up browser dev window, and go to console, and copy-paste whatever red error you're getting

Does this happen with every HaxeFlixel game, or only FNF?

[NotHyper-474]

Tried this on a template Flixel project and got the same result.

So it's an OpenFL issue at this point.

Use some environment variables can make game running with wayland. (See renpy/renpy#3290)

export SDL_DYNAMIC_API=/usr/lib64/libSDL2-2.0.so.0
export SDL_VIDEODRIVER=wayland

PS: Wayland is not supported now. may cause some problems.

[Stilic]

SDL_DYNAMIC_API=/usr/lib64/libSDL2-2.0.so.0

I don't have window decorations on Gnome.

You could install sdl library from package manager of system.
example sudo pacman -S sdl2

Sorry, this approach is wrong. See ArchLinux Wiki.

I've not had a problem with FNF under Arch in Wayland, I've not tested the vanilla game yet but outside of that, it seems to be fine for me

I already have it installed.

@Stilic Some wayland program missing titlebar on gnome, like vkcube-wayland (from vulkan-tools).
It happen on fnf?

There's a fix for that listed on the Arch Linux Wiki.
