MGP15 How to remove the dark shadow in the 2-stroke beginner event?

[vallespir]

At the Lusoil track in Qatar (night track), inside the playing window there is a dark shadow top left. It is a square and covers one-quarter of the whole playing window. Although it is kind of transparent, but very annoying when driving. It stays... How can you remove this shadow ? Picture attached.

The only track where I have this shadow square.

PS. I have an old nVidia GTX 260, DirectX 10.0 (caused by this graphic card most likely)

I don't remember this bug, and I'm pretty sure I played this challenge

Actually I have this square shadow only at the Lusoil track in Qatar (night track). Not on other tracks.
