After recently updating my MacBook Pro (14-inch, 2021, M1 Pro) to macOS Sequoia (15.6), my docking station sporadically disconnects and reconnects about once every 1-5 minutes. This causes my external screens to switch off for about a second, and my external drive to disconnect.
This has (obviously) completely broken my workflow, and I've had to resort to connecting two screens directly to the MacBook. I've had to completely disconnect the external drive for fear of corrupting due to the sudden disconnects.
I've seen other people report the same or similar issues here, and other places. I've tried all kinds of fixes suggested on various forums (reinstalled drivers, cleared preference files, etc.) without any luck.
To be frank, this is a completely unacceptable bug that needs to be fixed ASAP. I cannot accept that installing an os update completely breaks something as fundamental as connecting to external devices via a docker. Especially when this worked completely fine on macOS 13, and I was essentially forced to update because the (working) macOS 13 was no longer supported.

Basically, it looks like you need to use DisplayLinks dedicated "cleaner"

Before installing version 1.11.0. No other forms of cleaning/reinstalling have been able to solve this for me.
