I am using wsl nix-shell to execute vscodium and firefox
they run but tiling them is not possible.
nix-shell -p vscodium firefox --run "firefox && codium ."
with the above command both application window appears and work, but cannot be tiled easily.
Helloo, I have not tried Nixos with WSL(or WSL in a long time), but to my knowledge using GUI apps through WSL can be done thanks to: GitHub - microsoft/wslg: Enabling the Windows Subsystem for Linux to include support for Wayland and X server related scenarios (which is enabled?/installed? by default) and there seems to be an issue regarding window snapping and WSL windows.
This seems like a WSL issue, not a Nixos one to me, but I am out of my depth here.
