I don’t know how to submit a bug report. Is there an specific section for submitting 2.4 beta bug reports?
Yesterday installed the latest beta v188.8.131.5218 after updating PHD2 from 2.3 to 2.4 everything run smooth. However I found some strange bloom-like artifacts around bright stars. I thought that my camera has fried, however I took a couple if images with Maxim and everything looked fine.
AFAIK fast download is only active for frame and focus and not for capturing, but AFAICT fast download was active in capture mode.
Long story short, after unchecking the fast download option from the camera tab the artifact disappeared.
