I've experienced something like that as well. Depending on what you can do, try a different monitor and/or different cable and/or different dongle. I've managed to find a combination that doesn't do that anymore.
I have my problem with OWC TB3 dock and Dell P2715Q. I will try an older dock that I have in the office (Kanex TB2 Express; as the name says, it is TB2, thus extra dongle needed); but playing around with different TB docks can get expensive...
I use a Dell XPS 13 with 3 external monitors via a Dell TB16 dock (which uses external power). I wonder if that setting solves these M1 issues (via the extra power) or not. I understand CalDigit docks also have external power but don't know if there can be a subtle difference.
