SUMMARY
Dell dock WD19 constantly struggling to show and controlling external displays.
I'm using cachyos kde plasma on a lenovo thinkpad T480, connected to the dock
that has 2 Asus V277U displays connected to it. In the display configuration,
the windows for the external connected displays can't be selected and moved to
close the gaps between displays.. that I didn't make. It appears that while
booting into the OS, both monitors display until I sign in. Disabling the
laptop screen allows me to see both displays, but for some reason, having all 3
displays enabled causes the issue shown in the image attached.

STEPS TO REPRODUCE
1. Plugging in the DisplayPort/USB-C cable into the thinkpad
2. 
3.
