I have 2 screens - (1) DVI connected and 90 deg rotated 1024x1280 to the left of my (2) main 1920x1200 DisplayPort connected. I have specially crafted Xorg config (see Additional Information) for this setup. This works well, up to the login screen (sddm), then after login for no reason, resolution and position of DP monitor is changed to match the DVI one (see xrandr output below). I have to go to the systemsettings and increase resolution and move the DP manually. (see 2nd xrandr below) This used to work well in the past (no intervention required), and also I have feeling that this does not happen everytime. So either it's some intermittent bug or it broke with some update, anyhow it feels like KDE has "mind of its own" instead of respecting my setup in Xorg config. Also I have no idea which component is responsible for this, so hope you can reassign to different project if needed. Reproducible: Always Actual Results: Dual screen config is messed up. Expected Results: Dual screen config stays same as perscribed by X config / works on login screen (sddm).

"kcmshell5 kded", deactivate the kscreen daemon. It's likely what messes from your Xorg.conf, but having to fix settings everytime sounds like a bug nevertheless.
I've same problem: two monitors, before login everything is ok, views are separated. After login second monitor becomes a clone of the first one and both monitors are falling back to common resolution.
Duplicate of bug 343608?
Nope, there kscreen picks some (nonsense) reason because it's the bigger one and ignores(?) the other one, here it prefers to clone screens (and apparently doesn't save "corrected" settings) despite even accepting one screen to be rotated.
Confirm here, Dual Monitor, however sometimes it's booting fine: Screen 1: 1680x1050 (DVI) Screen 2: 1920x1080 (DP) (main) The following script restores the setup after the plasmashell has finish loading, this is however a nasty workaround: #!/bin/sh xrandr --output DisplayPort-0 --primary --mode 1920x1080 --pos 1680x0 --rotate normal --output DVI-0 --mode 1680x1050 --pos 0x0 --rotate normal --output HDMI-0 --off pkill plasmashell plasmashell & This issue only happens when using KDE on a dual-monitor setup. I haven't tried tweaking Xorg, since this is sometimes I want to avoid.
I do not reproduce it anymore on KDE: 5.24.0 Anyone confirms?
