Going fullscreen mode on youtube/twitch player causes display settings to fail.



  • After recent win10 update I can't use fullscreen mode of flash/html5 players on youtube or twitch. Because each time I press "fullscreen", it breaks display settings (brightness becomes very very low) and I have to go through display color calibration tool to fix it. Each time.

    It only happens on Vivaldi - I tested it in Firefox and it works fine, nothing breaks.

    I updated Vivaldi an flash plugin to newest versions - didn't help. I made clean installation of display drivers - didn't help.

    Edit: my DxDiag: https://pastebin.com/PSa5tutG



  • Judging by the silence, it appears that I'm the only one encountering this issue... That means it'll probably be ignored by the developers. Which I can understand, since it's only one person from the entire userbase. That is unfortunate.



  • No idea if someone could help but paste here what vivaldi://gpu says.
    I don't know if it also helps but try to disable HW acceleration in Vivaldi if it's enabled or play with Override software rendering list in vivaldi://flags

    Disabling hardware acceleration seems to fixed the issue! Thanks a lot for the idea!
