SIGTERM leaves output invalid state

[hholst80]

I tried running wl-screenrec as a background process and then terminating it with a signal. It does not seem to work. However, it works fine if I ctrl-c and have the application as a foreground process.

Yeah, we currently register a SIGINT handler (ctrl-C), but not a sigterm. Is it typical to use sigterm in this way? I'll need to read up on the suggested usage.

In the meantime, kill -INT pid should work

After some reading I agree with you, and I added this.
