Post too my experience which seems similar to yours. I only see such 'minute' freeze when i'm working with libreoffice-calc (5.3.1 actually); here it is with a more recent version on Zesty 64 bits. (gnome-session 3.24.0-0ubuntu1)
You report against gnome-session, and myself can't decide if gnome- session has to be blamed or if soffice is faulty instead. What is sure is that bottleneck somewhere. This is irritating, for example, when you enter many data, and then find that some was written wrongly because the 'buffer' was not able to continue writting the exact order you typed the data. ** Tags added: zesty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1676304 Title: Gnome hanging at random times for 1 minute or so To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1676304/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
