I fear that GNOME is not the source of this issue. I had a look in the settings and noticed that many shortcuts have been changed from default. I did not do this manually. One suspicion is that it might got changed when changing from Unity to GNOME in an Ubuntu upgrade.
After changing those shortcuts back to default, everything worked as expected. However there might have been some problem causing those default values to change. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849950 Title: Window shortcuts maximize, windowed and hide (Super + Up / Down / H) don't work To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1849950/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
