I have full access to one of the problem pc's right now because the user is on vacation this week.
This one is Windows 10 Version 1909, build 18363.900.
Fences version is 188.8.131.52 and it was up to date before I purged it.
June 25th is when this user reported the issue. He still has Fences installed but if I move an icon, they all go crazy. He only recreated 2 new fences. There aren't any program updates that I see right before the issue started other than an update to Chrome. He's on 83.0.4103.116.
There was a Windows update that was installed on the 25th but I did that in hopes of fixing the issue - and it did not. Prior to that no windows updates since 6/10.
The graphics is Intel HD Graphics 630 with driver date 4/11/2020, version 184.108.40.20642.
Restoring from a saved snapshot does not work either.
I will see if the other user will let me connect and gather info. If there is something I can try on the one where the user is off, that would be easy - just let me know. It does show some Dell driver updates available so I'm going to try that and will advise.
