Web Player Choppy playback & scroll volume

I have used Plex for a couple of years without issue. Recently, I’ve had two issues.

First, everything I try to play using the web player in Chrome is choppy. I’ve closed everything out, checked system resources, reviewed settings per forum suggestions, can’t figure it out. The only changes are the two most recent server updates. Any thoughts? (Quick run down: I have uninstalled/reinstalled. Enabled/disabled Direct Play/Stream. Checked network settings (nothing had changed). Videos play in other players fine. UW app works but I don’t like it.

Second, I would really like to see the scroll wheel volume returned at least as an option. It’s how I changed the volume and the more cumbersome hover and scroll is not the same.
