Unfortunately the decision to minimize on a loss of focus is up to the game itself, so that part is not an Ubuntu bug.
What is an Ubuntu bug is that desktop-icons-ng still steals and then quickly restores focus when an app goes fullscreen. This is harmless to most fullscreen apps but obviously not to some games. A proper fix might end up coming from mutter rather that desktop-icons- ng. I'm not sure yet. ** Summary changed: - Persistent loss of focus when an application goes full screen + Loss of focus when an application goes full screen ** Also affects: mutter (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1946307 Title: Loss of focus when an application goes full screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-desktop-icons-ng/+bug/1946307/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
