But happening on PS3 client. If I connect to the same server using a mobile + chromecast, and play the same movie - it plays fine, which suggests a client problem.
Re-installing the app has not fixed. Any suggestions?
I’m seeing this same issue as well. The video controls popped up at somewhat random intervals while streaming a movie from my Win 7 Plex server (ver 7.5.1) to my PS3 running the latest client version. I’d say the controls popped up about 20 times over the course of the movie. Connection from server to PS3 is ethernet.
In the forum Announcements section under “Plex for PlayStation 3 & PlayStation 4” there is a post dated April 25th, 2017 which lists a fix for the Playstation 4 application.
Fix on-screen controls sometimes popping up intermittently while playing back video
There has been no equivalent fix released for the Playstation 3, although it seems to be suffering with a similar issue.
