I also experience this issue. Was not there in 19.10 for me either. It's ONLY when setting one of the monitors to portrait mode.
Currently I have to use a workaround, running ARandR or "nvidia x server settings" after login to set the displays. But I can't save the settings to make them persistent. It would be nice to be able to use the monitor.xml to make the settings persistent. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874217 Title: Dual monitor setup with secondary monitor in portrait-right mode cause tiled windows to occupy 1.5 monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1874217/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
