Line appearing after using strokeweight()

So whenever I run this code:

color COLOUR3 = color(255, 255, 0);
String CURRENTSHAPE = "square";

  fullScreen();

A line appears where I clicked the clear screen button. Does anyone know why this is?

Using APDE to write and build code.

Thanks.

Hey,

Line 122 : line(mouseX-25, mouseY-25, mouseX+25, mouseY+25);

You want to get rid of that.

Cheers.

Thank you! I forgot to comment that line out after I finished with prototyping a triangle.
