I don't doubt you. I haven't personally had any of those problems except fixing the resolution. I use Xbox clone controllers.
I don't use the official dock, just one of the dozen random USB-C docks running around my house. My Deck is mostly stock, except for an SSD upgrade. I used to dock it about a third of the time I played it but now I've got a mini PC running HoloISO connected to the TV to play games remotely from my rig if I want to play on the big screen (I'm too lazy to walk over and dock it and someone who will remain nameless borrows the deck from time to time). HoloISO hasn't shown any of the problems either.
Luck of the draw, I guess.
Edit: removed the line about it being dead stock because I wasn't thinking about my SSD upgrade when I wrote it. I addressed it elsewhere anyway.
