I prefer that you not keep adding to a list like this. It is no longer tracking version correctly but makes tracking and following difficult. I prefer a separate post for every item except in a beta thread.
I just found this as well when looking into Bug with Crop: Source. I will track it there.
23 ) gifs are not being accepted in Shotcut. If you try to bring in a gif Shotcut will crash.
This is a new bug in version 20.04 on Windows with animated GIF. You can workaround this today by removing Shotcut\lib\mlt\libmltgdk.dll from your installation. It is high priority, and as a last resort I can simply remove that unnecessary module in the Windows build.
