Vivaldi and MATE Desktop
Installed vivaldi-preview-18.104.22.168-1.x86_64.rpm on a Fedora 21 box running MATE Desktop 1.8.1. All Fedora updates are up to date. No problems with the install :cheer: I noticed that Vivaldi does not obey my mouse over windows raise setting. I have the "Raise selected windows after an interval" set to 1.9 seconds. As soon as my mouse touches (or hovers) the Vivaldi window, the window is instantly raised.
