Still images destroyed

[ABH10]

I am running KiOS version: 2.8.0
I am using the following board/model: Raspberry PI Zero WiFi.
I am using the following type of camera: RPi Camera v.1
My KiOS unit is connected to the network via: WiFi

Streaming and stored videos works fine, but storing images ("Disk") seems to very often destroy the images. It is as if some chunks of camera rows belongs to an earlier frame. The same RPi and Camera didn't show any problems when running MotionEyeOS.
