Been struggling with this issue myself. As reported by everyone else, transcoding on clients other than plex web is fine. But plex web in chrome/firefox has issues. It does however seem to function fine within Microsoft Edge however!
I had started my own thread before finding this, but bumping this one up aas clearly it’s a long standing issue within plex web.
Weirdly enough I had no issues for a while after installing a GPU and it performed fine within plex web, it only happened after I attempted to load as many transcodes as I could.
Its fine if I just allow plex to decode with gpu hw, but enabling encoding with gpu hw breaks within plex web on ff/chrome.
Ubuntu 18.04, Nvidia 1650 Super with 460.73.01 driver. Server: 1.23.0.4497. Plex web 4.55.1. Bare metal.
