now that saving 32-bit livestacks works again I found something else. I noticed that some bright stars have a strange appearance:

This looks like there is some kind of overrun. However I cannot imagine why. Only 30 images were stacked. The 16-bit version of the same livestack saved at the same time via the sequencer (livestack saved with "All formats") does not show this.
