Menu screen not compatible with ultrawide resolution

The main menu and options screens are not compatible with ultrawide resolutions and display black bars on each side of the screen.
Ultrawide works fine once I load a game but the main menu always keeps a 16:9 ratio.

Tested with 3840 x 1600 and lower ultrawide resolutions.

i cant change the video settings in ultra wide as my cursor doesn't line up with the menu, preventing me from clicking apply changes.
