Hi guys  
I’m starting with Piston, I like it, but not sure why the window is bigger than the size I specify, even happens with the piston example Hello\_world  
that’s the code directly taken from github and running it, I changed nothing 🙂

Might be a minimum size imposed by the window manager?

Turns out is a Glutin issue, I switched the Window to use GLFW window and works great, even faster, using glutin I was noticing a lag
