Weird circle while playing trackmania

[AppenZ]

Hello,

Since today, there is a circle on the right of my screen when i play trackmania and i can't hide it, even with the * command. I don't know how it is appeared, i was just rollin on my kb and then i had this shitty circle... It is useless (i think?) and very uncomfortable to play with. I already reinstalled maniaplanet and my graphic card.

Do you know what it is and how to remove it ?

Thanks !

AppenZ, french player
