Even with great keying and compositing, it is possible to have webbed appendages and other flaws. A 2010 Google Summer of Code project added scripting support to KWin, but it suffered from a number of drawbacks. We take each pair of corresponding pixels, apply a certain compositing operation (we’ll discuss each possible operation in detail a bit later) on their channels and get a third pixel for the resulting layer. So disabling compositing is obviously not the silver bullet for being “lightweight”. It was, Gräßlin said, a prototype and one that should never have been merged. This has to go further than the current possibilities. Join longtime VFX artist, editor, software developer, and business owner Simon Ubsdell for Part 3 of the best look behind the technology of compositing that you've ever seen, packed with practical advice for applying the secrets of alpha channels that's simply not possible before understanding these underlying principles. So I expect this to be a driver / KDE issue. Volumetric data (e.g. Without compositing we move the time-memory tradeoff towards using more CPU (create those windows) to prevent even more CPU usage.
