After the release of Barracuda Opera uses the <link rel=”icon”> or <link rel="apple-touch-icon"> meta in the site's header to find the logo, but it will only show in Opera if the attached image is wider than 114px.
<link rel="apple-touch-icon" href="http://youriste.com/images/apple-touch-icon.png">
Which should link to a 158px x 158px or larger image.
Without this, Opera Speed Dial icons will usually also discover and make available to you the OG image if a website has one declared.
As mentioned above, warning of this is already mentioned in the permissions. Please check the "permissions" category, both on the addons page as well as well as the extensions management page in the browser itself.
Wait wait wait... it's an interaction between the chrome render engine and Windows, it seems.
I had the correct color profile selected in windows. Bad idea. Now I deleted it from windows, and now it looks just right. Thank god.
