I'm not sure what should disable the touch input when suspended... shouldn't the touch hardware be powered down with the screen?

I don't think groovenotify should be "affected" by this bug, reassigning to webbrowser.

affects: groovenotify → webbrowser-app

from irc this morning, sounds like the pause occurs due to greeter no longer being blocked (as in eglswapbuffers no longer blocking) in order to transition to the locked state. I suspect if the desire is to pause on screen blank in this case, its another instance of the playback engine needing to listen to Unity.Screen DisplayPowerStateChange to act immediately. otherwise, it'll need to be whitelisted somehow.

I think this is not related the browser-app, i am also seeing this problem when the music plays with the music-app, the music stops and i have to tap one or two times to make to play the music again.

with respect to tapping & touch driver, I believe it is this bug

Kevin, is this issue still valid?

Since we moved to Oxide, the situation is quite different. So I will mark this issue invalid. Feel free to re-open if you still observe this issue.

Changed in webbrowser-app:
status: New → Invalid
