I'm only noticing issues with YouTube currently.
When I watch normally through my browser, videos tend to desync over the course of about 5-10 seconds of playing and then there'll be a moment where it'll fast-forward or skip ahead to where it should be. This is taking place over multiple videos and I've restarted my browser and checked for other programs that may have been clashing. If I full-screen YouTube and watch like that, I don't see any real issues from what was normally.
This only started taking place in the past day or two when I restarted my browser and Opera updated. I've absolutely no concerns over PC specs or claiming it'd be hardware bottlenecking. I did, however, get a new router a few days prior. It's already updated on firmware and settings checked. I'm actively looking into that as a concern as well.
Any ideas to help debug where this is coming from?
