Logout issue - Beta drivers 2.6 and official drivers 2.5
 

I'm experiencing a logout issue using either the Beta drivers 2.6 or the official drivers 2.5 on a Macbook pro mid 2015 El Capitan 10.11.5 on a three monitor setup using an Etek city USB hub. Left monitor is a Samsung in regular standard display mode. The middle and right dell monitors are both in 90 degree mode (vertical).

Periodically when I drag my mouse to the middle monitor top left corner, the Mac logs me out with mission controlled enable in the top left hot corner. I disabled Mission Control in hot corners, but can still occasionally replicate this issue.

Using the keyboard shortcut for Mission control, I can replicate the issue when I drag a window in the left or middle monitor to move the window to another workplace. Right now, the issue is replicating each time I try to move a window to another workspace, but other times the issue doesn't occur. When I'm sent to the login screen, it says "Network accounts are available." I"m able to login with no issue.

I've replicated this issue with my Etek City dvi hub and an old USB DVI display adapter. I've tried uninstalling the beta driver and reinstalling, but the issue persists.

This issue never happened while using one or two monitors, and I was not using the displaylink driver before.

I uninstalled the beta drivers and went back to the laptop display and two dell monitors until this issue is fixed.

Issue Logs
 

My band aid fix was to not use mission control to move to a new workspace. I upgraded to Mac OS Sierra this morning.

I moved my DVI cables and swapped connections so my middle monitor has the 60hz refresh rate. The left and right monitors have the 30 hz refresh rate now. I tried moving the next workspace to the the right, and the infamous Mac OS Logout issue occurred.

I found someone with the same issue. A response tells you how to get to the Mac system logs.

The issue doesn't occur when one monitor hooks up. It appears this error is an issue with the MacOS libdispatch client and the displaylink software.

Update
 

I uninstalled the display link driver and rebooted. I've upgraded to a 2540x1440 monitor for my center monitor and am using a second 1920x1080p monitor. I'm happily using the Mission control and work spaces again. IMO this is a better solution for multi-tasking and productivity if you're experiencing any driver and Apple module issues like I have, and you don't want to take the mouse 30hz performance hit using the display link driver.
