Aurora UI Problem on Ultrawide Resolutions

[Serious Table]

I'm having some issues with Aurora and RealUI in relation to Ultrawide monitor resolutions. On Windowed (Fullscreen) or Fullscreen at a resolution of 2560x1080, I get the following error from Aurora, and RealUI's options are unable to be changed (among a myriad of skinning issues, such as the Main Menu not being skinned properly).

However, if I swap to windowed 1920x1080, RealUI and Aurora works as expected.
