10.14.6 Issues with Display Link Drivers

Well seems a number of people on 10.14.6 have discovered Display Link driver issues.

Firstly, on drivers 5.2 I can not use an external Thunderbolt Monitor. The drivers incorrectly work with the external dock and simply do not let thunderbolt monitors or HDMI screens off a thunderbolt dock function. Random start ups, maybe if you remove the connection to the dock you may get the monitors to start up...maybe.

Reverting back to driver 5.1.1 fixes the external Display issue and monitors from an external dock function as well as monitors that are connected to DisplayLink dock (swapping between them). However, what I have found on driver 5.1.1 is that if you use DisplayLink docks and then non-Display link docks that the process of swapping almost always sends the MacOS DisplayServer into high CPU usage. DisplayServer will sit at 30% usage and eventually increase to the point where the system kills it and restarts. This of course is after the Fans start and whirl for an hour or so....

Reverting back to driver 5.0 now to see if this is any better as obviously the last 2 have serious issues for myself. To be honest, given all the issues with DisplayLink drivers for Macs over the last release and an inability to get a stable working functional version I'd be happy if my work got rid of these things. Too much wasted time in trying to make things work.

I'll report back on how 5.0 driver does...cross the fingers that some thing will reliably function.
