Title:
  Taking picture crashes Snapshot

Status in gnome-snapshot package in Ubuntu:
  Confirmed

Bug description:
  When I take a picture, it immediately crashes. Interestingly, it
  successfully saves the photo before crashing.

  This occurs with a USB HDMI capture device
  (https://www.amazon.com/gp/product/B09FLN63B3). It does not detect my
  laptop's webcam at all, but that appears to be a known bug.

  I have attached a (10 MB!) GDB backtrace. It appears to get stuck in
  an infinite loop.
