Gräßlin: Client Side Window Decorations and Wayland
[Development] Posted Feb 7, 2013 22:47 UTC (Thu) by jake
KWin hacker Martin Gräßlin discusses client side decorations (CSD) and Wayland on his blog. He notes that while Weston—the reference Wayland compositor—requires CSD, nothing in the Wayland protocol does. "I had a talk with Andy from Qt Wayland fame about the CSD implementation and he explained [to] me that inside Qt the CSD code gives some overhead and that they have a flag to turn them off. Which is great. And we in KWin already have server side decorations and will need to keep them around for legacy X applications. What's the point then to use CSD in Qt if we already have the decorations and can give the application a better performance? Well none and that's why I plan to use server side decoration in KWin on Wayland."
