Wrong scaling of Vignettes/Loading Screen on Ultrawide Monitors

I´m using an 21:9 ultrawide monitor and I think more and more people are starting using them. 

The main manu scales just perfect with black bars on the sides. The gameplay itself works with ultrawide just perfect, no problem there, so thanks for your work! But the loadingscreen scales wrong: I should work like the main manu and have black bars on the side. Instead it distorts the image which is a bit sad, because I LOVE the artwork of DST, its amazing!
