Vivaldi 1.8 - still a snail
Nothing changed, unfortunately. Run Vivaldi for a day, then open a Google Sheet - takes minimum 10sec to become responsive and CPU is maxed out during that time. Force quit and restart with all the same tabs open and it takes only a second before you can start editing the worksheet.
Please report this as a bug.
