After clicking on "Finish recording" in Spectacle, the final webm file is saved, but sometimes it's missing some seconds at the end, it's like the video is not stopped at the moment when I click on "Finish recording", because I can clearly see the time counter is still increasing for a moment before stopping, then Spectacle becomes totally frozen for more than 10 seconds and is forced to close with the following generated crash:
