​Movie starts with audio but video is missing menu has graphic glitches

Hi all,

recently I updated to Libreelec 8.2 and noticed that I cannot play videos anymore, neither from hard drive nor from stream.

I can start the movie/stream with audio, but Kodi seems to stay in the home menu. It only seems, because in the right upper corner I notice that the movie is being played. When I press back or fullscreen, normally the video player comes in front. This does not work well, because I see the video menu (timeline, title, controls), but not the video itself. I am not sure whether I see the complete video player or only a part of it. But surely something is missing. And most often the video menu shows graphic glitches when doing its animation (moving all control elements out of screen).

Does someone know what happens here? How to check and reinstall the graphic stack?

I am running an old AMD E-350. In system menu all accelerations are activated. System information looks complete.

Well, as your hint was the release, I downgraded to 7.0.3. The installation worked like a charm. I was able to play movies again. But the userdata like addons was still updated with latest versions. I could not use this installation. Then I installed again 8.2.1. And you know what? Now the video is working again...

I don't know the installation routine, but certainly there was something not updated accordingly. I would like to know the reason. If someone tell how I could identity potential causes, I will try.
