# Problem

When starting capture, it causes SEGV.
It seems that it does not depends on supported formats.
gif, apng, webm, mp4, all of them will crash.

When using with --backend=ffmpeg, SEGV does not occur.


# Expected

No SEGV at all even though with gnome-shell backend.

# Actual

Here is the backtrace of it. (with peek --backend=gnome-shell)
