So I've updated dev to the latest again 3.5.99.15-0.0build1.1.git20180308.2971.main.fc27
And I seem to get an nxagent segfault every time I move the session window into another screen.
Same version in production and it was stable for a few days now. I could move it across screens. I suspended and resumed several times. But, after logging out of production and logging back in again, I'm back to segfaulting when moving across screens.
It's a very strange problem :-(
Executive summary:
The segfault on connect I have not reproduced. But its been reported by several of my users. I have around 50 logged in users at the moment. The login segfault only happens to very few (5/6). Some of them seemed to be working now.
The move across the screen segfault has happened to 3 users (including me) and all have been linux clients (Fedora I think). The move across screen segfault seems to go away sometimes for undermined reasons.

Fixing the bug could take weeks, so it would be good to roll back 1 version that seemed to be more stable while we wait.
The other version has a different severe bug, related to Screen Savers and DPMS. Make sure to disable them, if you really want to downgrade.
Thanks for those snapshot links. I manage to use them an roll back 1 version on the dev system to avoid:

I was about to roll back production, but users that were getting seg faults (on connecting or moving across screens) seemed to start working!
So I've left production alone for now.
Of the 5/6 users that hit these problems most of them seem to be connecting again.
Seg faults are still occurring in nxagent and some users still have not connected successfully, but most seem fine and get on after a few retries.
