Abnormal Colors in Valhalla

I purchased Valhalla some time ago and tried to play it on GFN. But I'm seeing these weird Borders in entire game. And the graphics are also not that Sharp and looks from 15 year old games. Idon't know where the exact problem is.

I played Cyberpunk, Finished Odyssey, Mirage and other games on same device, never faced an issue. Only with Valhalla.

Any ideas how can I fix it.
