Bug#1092939: x11-xserver-utils: xranrd show screen resolution but disconnected.

I am still facing the issue, this time I can see the 2 external screens as "disconnected", even if they are connected, and with a resolution listed for both.

DP-3-1-1 disconnected 3840x2160+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
DP-3-2 disconnected 3414x1920+0+240 (normal left inverted right x axis y axis) 0mm x 0mm
3840x2160 (0x540) 519.940MHz +HSync -VSync
h: width 3840 start 3864 end 3880 total 3900 skew 0 clock 133.32KHz
v: height 2160 start 2163 end 2168 total 2222 clock 60.00Hz

Trying to "remove" the monitors is throwing an error. Trying to remove an empty one failed as expected.

Any idea what I can look at?

When connecting my laptop to an external hub with 2 screens, I'm getting the following xrandr output:
DP-3-2 disconnected 3414x1920+0+240 (normal left inverted right x axis y axis) 0mm x 0mm
3840x2160 (0xec) 519.940MHz +HSync -VSync
h: width 3840 start 3864 end 3880 total 3900 skew 0 clock 133.32KHz

DP-3-2 is the right ID but it shows as disconnected. It is also showing only a single screen.
After a computer restart, everything is showing correctly. Also, when running xrandr on the command line, the entire screen is freezing for a few seconds. This is causing issues to xfc4-display-setting to work correctly.

Here are the outputs.

With 3 screens, 2 on the hub + laptop, before restart:
