Twitch video stream lagging on new window instance

  • Heyo fellow forum users

    I'm writing about my problem here, because I think this post could help someone in the future so I want it visible for everyone.

    I've encountered a bug, which occurs when I open a new window by drag-and-dropping a list with a Twitch livestream on it or right clicking that list and choosing Move list to -> New window. When new window opens, whole page starts lagging really heavily, not only a stream, but all animations too (eg. writing a message in chat). This bug doesn't disappear on page refresh BUT when I open a new fresh list in a window with lagging list, it's working properly. For me, this is reproducible on any twitch live stream.

    I'm running a double monitor setup one with 144Hz and one with 60Hz. It doesn't matter what combination I use (old and new window on 144Hz; old window on 144Hz and new on 60Hz etc.) it's lagging all the same.

    I've tried disabling/enabling gpu-blacklist and software acceleration flags and disabling/enabling hardware acceleration and use animations in settings.

    This is first time it's happening, it does work normally in Chrome and Firefox browsers.

    Technical specifications:
    Vivaldi version: 2.4.1488.36
    CPU: Intel Core i5-8400
    GPU: GeForce GTX 1070 Ti

    @gaelle @Myliak I already reported this a while ago, but it was marked as CNR (VB-50885). The same thing can also happen by tiling the page.
