Profile not properly applied, at least in Xfce

[mprz1024]

Using autorandr 1.15, Xfce 4.18.6 and Debian Trixie (xrandr 1.5.2, Xorg 7.7, RandR 1.6).

1. On my laptop alone, with zero cables connected, I setup screen resolution and saved the profile with autorandr --save default
2. I connected an external monitor on DP-4, and in xfce-display-settings I've put it to the left, bottom-aligned, then saved the profile with autorandr --save laptop+4k
3. If I unplug the monitor, wait for autorandr to do its thing, then plug it back and wait again a few times, sometimes the laptop+4k profile will not be loaded properly, with the screens overlapping instead of laid next to each other as I saved it

When that happens, autorandr says it has detected and applied laptop+4k properly, and if I reapply it with autorandr --force laptop+4k, nothing gets fixed and the positions are still wrong. The only way to make it work and put the monitors where I saved them is to switch profiles with: autorandr --force laptop; autorandr --force laptop+4k

In Xfce display settings, Advanced, I have no profiles and I have set "When new displays are connected" to "Do nothing", and "Automatically enable profiles" is unset. Could this still be a conflict between Xfce or X or whatever else and autorandr?
