Some HTML stream and videos won't play properly
Twitch and YouTube streams and facebook videos will play only sound while the screen will stay black. On demo.castlabs.com it affects only Smooth Streaming, unencrypted demo, while Smooth Streaming, DRM is working as expected. I already tryed solutions i found at other posts(reinstaled Flash, launching with --disable-gpu-sandbox flag) but none of them works. Any ideas?
I actually fixed it by disabling hardware acceleration. There is how to do it if someone has the same problem( it was caused probably by swithable AMD Radeon graphic card):
1. Go to vivaldi://flags/#disable-accelerated-video-decode
2. Click Disable (or Deactivate, i use localized version so i do not know what is written there in English)
