What’s with the blue thing on my screen? – Anger of Stick 5 : zombie Review

Anger of stick is one of the best Stick fighting I have ever played but all of a sudden this thick blue line shows up on my screen and makes the game unplayable, Even when I downloaded the other anger of sticks the blue screen is there too! Please fix this it’s a really good game and I wanna play it.
