Anyway, after rebooting with the above two changes, Slack no longer causes DisplayLinkManager to chew up my CPU like it did before.

I have not fully tested things but I'm hopeful things work now.
Thank you very much for posting the findings. I'm also using DisplayLink device with ElementaryOS (Ubuntu Xenial based release) installed on a Macbook Air, and faced to the same issue set.
And noticed the miracle when killing the Slack and the CPU clams down.

Also followed the FAQ solutions and AFAIK the issue is gone for good. Lets see on future.
