Has anyone ever used those things for more than a single day? I honestly thought the current compositing window managers don't even support that novelty stuff anymore.
In the context that's not the point -- another plus for client-side decorations is that no synchronization is needed between the decorator and client for resizing.
Personally I think client-side decorations are far easier to implement reliably and would welcome them becoming default.
I use wobbling windows because it makes my interaction with the system seem more transparent. Rigid windows feel unnatural, but wobbly windows let me become absorbed by my task.
