Tearing in all games and instable fps in Xenoblade

[Cyberratchet]

I've updated to the latest dolphin version today and the issue is still here.
What's really weird about the tearing is, that the fullscreen borderless mode seems to eliminated the issue ... if it works. If I start dolphin, I have to change something in the graphics menu, start the game, stop it and revert the change, then the tearing issue is gone.
That's obviously not optimal, because I usally start dolphin via the cmd (emulationstation) and I dont't want to see dolphin's gui to begin with.
