Ok, I did a file audit (Windows). What I found was that these changes come from Hugo, not another program. They are triggered by a normal server update and happen exactly one second later:
Me saving an md file:
Change detected, rebuilding site.
2020-10-16 11:28:09.277 +0200
One Second later a change on a couple other files is detected. For example all my svg or all my json
Change detected, rebuilding site.
2020-10-16 11:28:10.277 +0200
This is the Handle Manipulation, which comes from an attempt to duplicate a handle to an object. This belongs to the first saving.

Beschreibung:
Es wurde versucht, ein Handle zu einem Objekt zu duplizieren.
Quellhandleinformationen:
Quellhandle-ID: 0xb9c
Quellprozess-ID: 0xb98
Neue Handleinformationen:
Zielhandle-ID: 0x6114
Zielprozess-ID: 0x4
Source Process ID 0xb98 is PID 2968 and this was Hugo
Target Process ID 0x4 is PID 4 and this is System
After this, each file gets four Event IDs, 4658, 4656, 4663, and 4658 from Task Category File System.
1 second later, the procedure is repeated.
To sum up, I have no idea whats going on, but the files are not really changed though a change is detected. I assume it relates to this Handle Manipulation. Maybe it has something todo with caching.
