Do you guys have any idea how to fix this 21:9 issue for Five Guardians of david game ?

It uses unity engine and if I play it in FULLSCREEN it stretches out and lowers the sharpness of the game.

You can use the Borderless Gaming app although it fails to hide the window's top bar for some reason.
The best solution is to open Five.exe in a hex editor, search for 398EE33F (2 tokens in the file) and replace with 8EE31840. I used the same method to play in Surround, will post a Detailed Report in the near-ish future.
