Radial mask feather not working since last upgrade. V9.4.1

Hi @MarcB, Welcome to the Lightroom Community forum! We have seen several reports of unusual masking behavior, so we are investigating the issue. However, we could use some more details to help with our investigation. Can you send your system info, a screen recording of the issue, and a numbered list of the exact steps needed to replicate it? You can find your system info by going to Help > System Info, copying and pasting it into a text file, and attaching it here. Thanks! ^CH
