I have two displays side-by-side: one that is 2560x1440 in landscape and a second that is 1280x1024 in portrait. In earlier versions of Ubuntu (definitely in 19.04 and 19.10) I was able to configure this using Display Settings in the default windowing environment.
After upgrading to Ubuntu 20.04 it seems Display Settings is computing an incorrect horizontal resolution for the combined display. This results in a display that is too wide for the monitors that pans when I mouse toward the edges.
xrandr is reporting that it's trying to make a display that is 3840x1440 (2560+1280) instead of 3584x1440 (2560+1024), so I assume something is doing the math before considering the smaller display is in portrait instead of landscape.
here is the output from xrandr:
