Black window?



  • Vivaldi runs fine ordinarily but when I have a particular game running, and launch Vivaldi, I get a plain black window with nothing in it.

    Other browsers (whether chromium based or mozilla based or even Edge!) don't have this issue, they work fine alongside the same game.

    Any clues?



  • Hi,
    first of all it would be good to know what game in particular does this - with a link if possible. So we can have a look if this happens only to you or if other users get the same result.

    Next we need to know what version of windows and vivaldi you are using (you can look up the vivaldi version in the first line at vivaldi://about)

    What extensions do you use?

    What security software do you use (antivirus, firewall, etc.) because there had been some issues in the last few month.

    Does the game need a installed Pepper-Flashplayer (PPAPI)?
    See https://help.vivaldi.com/article/install-flash-player-for-vivaldi/

    Did you allow Flash content on the page?
    Hit the icon at left address field and for Flash select dopdown "Always allow on this site"



  • It's not flash. The game is "Uncharted Waters Online" although it's a biggish download... also I won't be responsible if you spend the next year or so playing it :D Currently being run by Papaya play: https://uwo.papayaplay.com/uwo.do
