MicrosoftEdge
[Problem/Bug]: After a period of time, the video element will not display the picture and only play the sound.
What happened?
I embedded a video player element in a webpage, hiding all of its controls, such as the progress bar and volume, and used it as a dynamic background for the page. The video would also switch between them periodically. I found that there were no issues at first, with both the video display and the sound playing normally. However, when I left the computer idle for a while, I noticed that the video no longer displayed, while the sound continued to play normally. I would also like to clarify that the computer did not automatically hibernate or sleep when idle. When encountering the above situation, refreshing the page cannot solve the problem. The video screen is still not displayed, only the audio is played. It will return to normal only after restarting the process.

hi @HHGGHH1995 can you please provide the SDK Version and the respective sample app you are referring to which you are facing issue. If possible, please provide the video or a screen shot of the bug you are facing. Thankyou
I have the same issue, i've tried many SDK versions including the latest, all present the same issue. Issue has started to occur since Build 139.0.3405.102 of the runtime has been "evergreened" onto our devices
The failing devices are win10 IoT Enterprise LTSC. Seems fine on Standard editions of windows (in my case)
