I've tried kwin's XRender mode a few times and found it to be essentially useless because it's too slow. But I can't tell which part of the graphics stack is to blame here: the crappy Radeon HD 4200 IGP, the open source radeon driver, kwin or something else.

I've only ever used when using KDE in a virtual machine, be it parallels, virtualbox or vmware: in all those cases, the xrender backend worked pretty well.

Did you use any of the animations, such as the minimization effect? Because on my machine, those were always jerky and unpleasant.
