Ultra-Widescreen Overlay and Digidash

[MaSi5500]

I use Richard Burns Rallye with FixUp Plugin. The car and track has the correct aspect ratio - but the overlay like the digidash, time, menus and direction boxes looks crushed.

I have seen some Ultrawide Youtube Users which have fixed the problem. But google helped me with any resoluts. Maybe some of you have an idea?

Aspect is 25:9 2560x1080 thx
