[Bug 1518935] Re: When an application is suspended or closed it causes a large UI stutter
So I think that the answer is, yeah, we do that syncronously. We do a dbus call to cgmanager to get the list of pids and try to write their proc value. If we fail, then we need a setuid helper for things like oxide. So it could be that spawning that helper is part of what is causing a delay I'm not sure how to do it another way though. We're not blocking on it running, the overhead is just starting it. ** Also affects: ubuntu-app-launch (Ubuntu) Importance: Undecided Status: New ** Changed in: qtmir (Ubuntu) Status: Triaged => Opinion -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1518935 Title: When an application is suspended or closed it causes a large UI stutter To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1518935/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Agreed, from playing about with this for a while now, anything that is using oxide (webbrowser or webapp) seems to cause a very large and noticeable delay.

In my case, I was continuously switching between Telegram and Twitter apps (post a tweet, then switch, chat a bit, then switch, etc)...could it have something to do with the browser?
