Bug Description

Since I upgraded from Ubuntu 19.10 to 20.04 my multi monitor setup is broken. I put the screens into the shape of an H. The center screen is in landscape and to each side one screen in portrait/pivot orientation. I expected to rotate the virtual screens of the outer monitors into portrait mode as it was possible before.

Instead the smallest (middle) screen gets scaled extremely in, the virtual screens overlap and just everything about the monitor setup breaks.

The resolutions are from left to right 1440p, 1080p, 2160p.
I could configure the outer screens to portrait mode over Nvidia X Server, but it doesn't survive a reboot. Also it breaks if I touch the screens over the gnome-control-center.
