The main menu of the game is very quickly replaced the background (Euro Truck Simulator 2)

In the main profile menu(where orders, settings, etc.) the background is very quickly replaced and much more(bring a video where everything is clearly visible), short speed up time. In the game driving everything was fine and I had decided to neo bramati attention to it, but after a couple of days, the truck was quicker to gain speed(the truck have not changed anything) and collars of steel clicking is much faster.
P. S
***Before all this started changed in the config some of the settings, went into the game and started I immediately !all! put it back, but nothing has changed***
