Hi,
Apologies for the wait.
Unfortunately, I haven’t been able to reproduce this where I use a “Set Input Mode Game and UI” node to flush the inputs in 5.4 and just using “Flush Player Input” in 5.5.
If I flush inputs and keep holding spacebar it continues on and closes the popup widget I made as I bound the next mapping context to close the popup.
It continues on if I have the action binded to triggered, but if I have it set to started I still only need to press space bar once to close the popup.
Would you be able to provide a small example project of this issue?
If not, another option could be to bind the mapping context to when the key is released.
Regards
