Can't setup monitor after reconnecting ThinkPad T570 to USB-C dock

I've got two monitors connected via DisplayPort to the dock. xrandr displays the external monitors as DP1-1 and DP1-2 and the laptop as eDP1.
I set up my monitors with the following in ~/.xprofile:
xrandr --output eDP1 --same-as DP1-1
xrandr --output DP1-2 --right-of DP1-1
This works fine. When disconnecting the laptop from the dock the laptop screen does the right thing, reverting to a single monitor. When reconnecting the laptop DP1-1 shows up, but DP1-2 remains blank. . ~/.xprofile changes nothing, and no error message is printed. I tried reconfiguring using the --crtc option, but all I ended up with were complaints that crtc-1 (or something similar) was not configured correctly. After trying a couple things I got "xrandr: cannot find output 0x46", which I can't find any precedence for.
After reconnecting the monitors have the same names ("DP1-1" and "DP1-2") and both of them are shown as "connected" by xrandr.

I may not have direct answers but few pointers which I want you to try. 1. (Mons package)[github.com/Ventto/mons] 2. adding hotplug configuration for monitor. and running xrandr when detected.

you can try github.com/codingtony/udev-monitor-hotplug. I feel this is better way because this way we can always execute when some device plugged in or out. whereas when we do it using ~/.xprofile it will execute only once on start of x-server. I am not claiming it cannot be done that way. just this is more convinient way to write logic(this is just my personal preferance).

@mattia.b89 After filing probably hundreds of bug reports in open source projects I haven't the faintest idea what or even where to report this issue. Is it a bug in X, the Intel driver,xrandr, or some other component? And in my experience the amount of work involved in writing such a bug report which will be fixed is about the same as learning to program it myself.

In my experience, it sometimes works to issue xrandr --auto after connecting to the dock again. This brings up the external monitor 3 out of 10 times at least.
Also logging out and then in brings the monitor back to life.
