Comment 37 for bug 1825593

I can confirm this bug remains even without Fractional Scaling is enabled, and also while using Wayland not X11

In my case I set monitor 1 as primary monitor (primary display port), monitor 3 (secondary display port) with orientation "Portrait Left", after reboot/logout/system update that required reboot, login window appears on monitor 3 in landscape mode, likewise after login monitor 3 is in landscape mode and the primary monitor (has the dock)
