Vivaldi 5 starts blank

The new 5th version of Vivaldi Linux browser starts as a blank window, though. Perhaps because of some compatibility issues, as seen in a logfile:

unsupported prctl PR_SET_NO_NEW_PRIVS
syscall inotify_init not implemented
unsupported socket(AF_NETLINK, 3, NETLINK_ROUTE)
unsupported getsockopt level 6 optname 11
possibly incorrect MADV_DONTNEED

I apologize for my haste — after two restarts Vivaldi 5 works as expected, cheers!

can I ask how did you manage to upgrade it ?

NomadBSD OpenBox menu Network: Linux Browser Installer GUI: [Upgrade browser(s)] — not Install.

ah ok, I forgot the upgrade option, thank you
