My MacBook Pro (13”, 2017, Two Thunderbolt 3 ports, Mojave 10.14.5) is doing something weird when I try to use the hidden dock with some external screens.

Never had the problem before, but ever since hooking up to an HD screen (temporarily), my dock isn’t working properly with other second screens.

The dock doesn’t show up until I’ve held the cursor in place for 5–15 seconds on either screen, and even then it sometimes doesn’t appear. I’ve regressed to an unhidden dock for now, but this is not ideal. I’ve tried adjusting resolution size and a few other things, but nothing is working so far.

When I’m not using a second screen, I have no problems at all. Research has not giving me much to go on.

Thanks for your answer. I think that this was more an issue with the admin account. I made a new account with admin priv and that one was ok, so I must have screwed up the admin profile. Re-do has fixed it.
Thanks for your help!
