Use the breeze decoration.

There's a known bug in QtQuick 5.6.0 (supposingly fixed in 5.6.1) that will make it segfault on randr events, though the traces would look different.

> However, need configure dual screen configuration using xrandr
What does this mean? The dualscreen setup isn't configured on login and you need to call it by hand? Or that calling xrandr will make the next appearing window crash KWin?
