[Problem/Bug]: After a period of time, the video element will not display the picture and only play the sound. #5342
Description
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.
