Xbox controller in pc turns left by itself

[alccad]

Hello, I am an occasional player of f1 games on pc and with f1 2019, just purchased, a very strange thing happens to me. I use the xbox controller to play and suddenly, especially on straights, it turns to the left by itself making the game unplayable. It does this with both controllers I own and with no other game, not even previous f1s. The game is in Steam version, updated to the latest version. Updated controllers. I have read here and there that it also happens to others but what is the solution please? It is very frustrating. Thanks.
