Straight Mode BUG

Through out 3 races my staright mode starting doing wierd things . Closing and oppening by itself and bogged me down ... And the last time did to me was in Bahrain and in every SM sector done the same and the cars was passing me like stopped ... It need to be fixed ASAP ... I can't enjoy it like that... I repair the game files , i reconect every thing from my simsetup , i restart my pc and nothing changes ... I even remake everything in the controls scheme and nothing changes . ( This happened in my driver career mode , only mode i played ,  but im sure its also in all the game modes )
