What version of Janus is this happening on?
Put the version and the commit identifier (available in version.c or from an info request) here

Have you tested a more recent version of Janus too?
Yes/no. If yes, which one. If not, why.

Was this working before?
If you have information on a version/commit where the issue wasn't there (e.g., the result of a git bisect), please provide it here.

Is there a gdb or libasan trace of the issue?
If you have a trace related to the issue (e.g., after a segfault), provide it as a gist/pastebin/other link here, or as a collapsible section. Do NOT paste logs inline. For more information on the kind of traces we may find useful, please refer to the documentation.

I have a video room, and if someone leaves the tab, their video is interrupted and a black screen appears instead of their stream
