still happens in 17.04. This happens if using the Ambiance theme with gnome-flashback, so I think it is theme related and not specifically any app window. You can work around this by modifying your .config/gtk-3.0/gtk.css file to leave some margin space around your window, like:
.background.csd decoration { margin: 10px; } [see https://askubuntu.com/questions/733466/cant-resize-nautilus-window-in-gnome-flashback-using-ambiance-theme for more info] -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1579142 Title: Evince windows cannot be resized after upgrade to Xenial To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1579142/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
