Default Second connected monitor doesn't display anything

I don't know if this is evdi or manager issue, so here's a copied report:


- Are you using the latest driver?
How would I know? (possibly - I had to use the unbundled build for the rpm)
- Are you using the latest EVDI version?
1.9.1
- If you are using a DisplayLink device, have you checked 'troubleshooting' on DisplayLink's website?
Yes
- Is this issue related to evdi/kernel?
Unknown

- Linux distribution and its version
Fedora 34
- Linux kernel version
5.13.13-200.fc34
- Xorg version (if used)
xorg-x11-server-Xorg-1.20.11-1.fc34.x86_64
- Desktop environment in use
KDE/plasma

I've got two Dell monitors connected to the Lenovo hybrid USB-C dock.
The xrandr layout is:

Monitors: 3
Code:
 0: +*eDP-1 1920/344x1080/194+297+1440  eDP-1
 1: +DVI-I-3-2 2560/597x1440/336+0+0  DVI-I-3-2
 2: +DVI-I-2-1 2560/597x1440/336+2560+0  DVI-I-2-1
The monitors are:
Code:
DVI-I-3-2 - Dell S2721DGF
DVI-I-2-1 - Dell U2715H
The 3-2 works fine.
The 2-1 is blank. Neither the cursor nor the windows are displayed on it.

There are no messages in the displaylink journal beyond the standard start/stop. Nothing suspicious in system journal either.

Dmesg has only:
