I seem to be experiencing flickering when broadcasting/previewing.
There's no crash or anything like that but it is really annoying to have it persist.

I don't particularly see any issue with the log file, you may have to post a video of the issue.

It looks like you're streaming at 720p, but are running your camera at 1080p. Sometimes 1080p on a USB 2.0 camera can cause performance issues, so can you try lowering your camera resolution, too?
