Glad it’s not just me!
I opened a ticket as well, but I think they just chocked it up to the dock, but that conclusion isn’t consistent with my findings.
I also ordered a 165W PD 3.1 Charger to see if it has something to do with the higher wattages. Will check this weekend
I didn’t think to check frequency, but that checks out, I’m getting the exact same behaviour. Where usage usage increase in the histogram is where I plugged in my dock using the fw16 charger.
I’m not entirely sure it’s the charger, it’s possible it’s the laptop firmware/onboard pd controller. I tested the fw16 charger and my dock on my old laptop, and had no issues.
I did find this in the logs; I ran dmesg while disconnecting/connecting the charger.
Here is the output when connecting the 180w directly to laptop (port 1)

Here is the output when connecting the 180w charger to the usb hub which is connected to port 4.
