Sometimes kanshi does not restore display config when re-docking

[luispabon]

I have a laptop which I connect to a thunderbolt dock with 2 additional displays. Ocassionally, when I re-dock the laptop, display position is not restored - displays are configured to be linear left to right instead of two top and one bottom as per my config. Killing kanshi and reloading it correctly restores display configuration.

I'm not sure what to do for debugging this further - it does not always happen.

Config:

# Laptop display by itself
{
    output "Sharp Corporation 0x1476 0x00000000" mode 3840x2160 scale 2 position 0,0
}

# Laptop display + studio 24"
{
    output eDP-1 mode 3840x2160 scale 2 position 0,1081
    output "Iiyama North America PL2410HD 11046A0B03094" mode 1920x1080 scale 1 position 0,0
}

# Laptop display + studio 24" and 19" via dock <-- this is the config that fails to apply upon docking
{
    output eDP-1 mode 3840x2160 scale 2 position 0,1081
    output "Iiyama North America PL2410HD 11046A0B03094" mode 1920x1080 scale 1 position 0,0
    output "Samsung Electric Company SMB1920NW HMDB101546" mode 1440x900 scale 1 position 1920,0
}

You can see at 16:02. Can't match profiles, but weirdly then it goes on to say applying profile [ line 13] which is the correct one, but it doesn't get applied.

If I kill kanshi & start it again, it works normally again.
