Speeddial thumbnails: give it more time to load when creating them?
I 1000% agree. I had posted about this as well and got no responses: https://vivaldi.net/en-US/forum/all/9145-speed-dial-thumbnail-improvements
This is a huge flaw in vivaldi's speed dial implementation IMO, I won't be moving away from opera until this changes
You don't have to recreate thumbnails everytime you delete top sites, just make a zipped backup of it once you rebuilt it, and just replace it when it is about 30mb. Mine is just 2mb with all thumbs (some personalized)
With this mod it's super easy to use your own pics for SD thumbnails
