Overlay is from tmp sow not an error from scs side. Also i had contact whit tmp after i sent a report tickit and they said that the developers are aware if this and they looking for a fix after the final dx11 version. Testen now openGL and your are right the overlay is nomal but game freezes in a weird way graphic wise hahaha could it be because of road to black see dlc? Lol
Edit: yeah it's openGL that fixed the overlay but thats causes the game freez sadly. Well i drive without chat and tab screen for now
