Indeed, the only thing I have found to work is to use the _input( event ) function and poll input using event.is_action(); event.is_action_pressed() and event.is_action_released() still do not work, however.

this issue (on Lubuntu 17.04 64bit) emerged form in the commit 3c17511 and afterwards.

in the previous commits ( f2a335d ), the .is_action_pressed/released works fine.

@alexwbc You must be wrong somehow. That commit has nothing to do with Input or InputEvent classes.
