This is something that used to work when enabling the settings "automatically capture the mouse in full-screen windows" and "emulate a virtual desktop" but now it no longer captures the mouse nor keyboard inputs. The mouse clicks are still detected though for some reason. the only thing I can see which is related is the output
but that doesnt seem like it should be an issue as there is no gamepad or controller. As far as I can tell, nothing related to inputs seems to be reported.
