Ah I had the same issue. JavaFX still uses X11. By default VSCode only lets X11 be used if Wayland is not available (this is the X11 fallback permission). Disabling X11 fallback will let VSCode use Wayland and let JavaFX use X11. I might make an issue for this on the flatpak’s GitHub asking for this change.
Honestly, the truth is that setting up containers for development will always be a hassle. My low tech way is just to make a distrobox container with its own home folder, install an IDE in it, and install packages. The more proper way to do it would create your own containerfile to build your container for developing.
VSCode also has its DevContainers extension but that doesn’t work in VSCodium and does some weird things.
