We have an issue with GPOs during gpupdate. When a group policy is processed, which adds a net share, then e.g. the calendar side pane in Outlook starts to flicker. Also an other application which we're using for accounting flickers a lot at that time.
We're using Windows 10 and Domain Controllers are running on Windows Server 2012
It happens if I run
gpupdate with a user who has group policy settings for:
1. adding, updating, or creating net shares
2. running registry settings
Other group policy settings does not lead to flickering.
There is nothing logged in the eventvwr.msc at the time of the flickering, except the gpupdate logs. I don't think it is a display driver problem either, because on we have the exact same problem on multiple hardware.
Are there any suggestions, what the problem could be and what I could investigate further?
