Could you do me a favor and issue this command in the terminal while the camera is capturing?
dmesg -wH
It will show if a reset is happening.
I can confirm that I also see this on my raspberry pi 4 running astroberry or stellarmate. I can reproduce it on a variety of versions of indi and kstars
Indi: v1.9.5, v1.9.7, v1.9.5.8, master
kstars: stable-3.5.9, stable-3.6.1
It may be some sort of issue with my particular camera, or it may be happening to all zwo 1600's. I'm still able to use the camera, it just slows things down, and may cause other issues.
