Full Screen Bug?

[nismo400z]

I have an Ultrawide monitor (Samsung G9) and while the game looks beautiful, even though I am in full screen mode (5120 x 1440) my Windows taskbar still shows along the bottom of the screen.

Yes, I've maximized the window, tried changing to 5120 x 1700, alt + enter, etc., to no avail. Is this a known issue or is there a work around? I have 7 other simulators and this is the only one with that behavior. I've included an attachment of the issue.

Apologies for the small resolution attachment, this website doesn't like Jpeg files
