I don't think this can be a Terminator bug, we aren't doing anything special when we are maximised. It might be worth checking your terminator preferences to see what the background setting is - perhaps it's set to be transparent and that is placing a high burden on your X server? Seems kinda unlikely though, given the kind of nvidia card you have.
