Wrong fov for 16/10 screen

[MrStefan]

Hello,

The horizontal fov is not calculed correctly in 16/10 resolutions.

Notice how the vertical fov is correct, you can see more content vertically on the 2nd screenshot, but less horizontally.

It's clearly visible something is wrong by looking at the hotbar, the last icon is not on the same row. It looks like the screen space is "compressed" horizontally.
