The main idea here is that if the theta parameter can change in space and time $\theta=\theta(x,​t)$,​ the term $\theta F \tilde F$ directly influences the equations of motion. This is discussed explicitly in Section 1.2 "The Theta Term" in [[http://​www.damtp.cam.ac.uk/​user/​tong/​gaugetheory/​gt.pdf|Tong'​s lectures on gauge theory]].
