So I've got the AskUbuntu chatroom (I'm just using this as an example, I've got other webapps that I've got the same issue with) saved as a "Application Shortcut" in Chromium, and the icon is really (And I mean really) low resolution. Example:
The top one is the default icon that's used for the Application Shortcut, the bottom is the AskUbuntu lens - so my question is, how can I use the icon that's used for the AskUbuntu lens.
