Thank you for your instructions. I followed them but there’s still a weird problem. As you see in this screenshot, subtitles and audios are played normally but the video image remains missed. I also tried to uninstall the browser and scroll back to version 0.69.135 Chromium: 77.0.3865.120, but the video image is still missed. It never happened before I update to the latest version.
Finally I found one way to solve this problem:
1.I uninstalled brave browser, set the default browser to chrome
2.relaunch my pc and installed brave 0.69.135 Chromium: 77.0.3865.120
3.launch brave and the video image was played normally for the first time. But when I relaunch brave browser, it failed again.
4.I also tested the latest version of Chrome and it didn’t reproduced. Video images were normal.
I doubted that this might be an individual problem on my pc. And it’s on Win7x64.
Hope you can reproduce this issue and work out the solution, but don’t be worry for I’ve found alternative broswers for temporarily use. Thank you for your investigation. Zhu.
