DirectX11 vs DirectX 12 Menu bug. Very dark menus. Brightness doesn't adjust

If i remember correctly, the problem started with an update sometimes in January.
I used DirectX 12 before that with no problems.
I have the same problem now just with the Sapphire Vega 56 driver 19.3.1.
Back then i found out that if i use DirectX 11 it was ok, but my problem now is that after another update DirectX 11 crashes the game a lot in every round while it does not seem to crash in DirectX 12.
So I'm looking forward for the UI fix.
