I have encountered this problem too. It happened with a freshly installed Ubuntu-GNOME 15.04. Now with Ubuntu-GNOME 15.10 and gnome-staging ppa it's still there. It's a real pain. You wait for the menu to appear then you click and wait for the menu to disappear again. As RK mentioned a reboot helps also restart of gnome-shell helps (Alt+F2, r) at least for a short time. But in contrast to RK I don't see anything unusual in syslog. I'm working on several AMD APU desktop systems with open source radeon driver. I tried Mate 1.12 from ppa and there the problem is not present. All modal dialogs and context menus (right click) appear fast and disappear the same way.
How can I help to track this issue down? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1514357 Title: Opening new windows or menus (e.g. "File") in programs, switching workspaces becomes slower and slower over time in Gnome To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1514357/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
