  The idea that I have in mind ATM is to redirect drawing the whole screen into a FBO and then draw it screen by screen applying transformation where necessary. This should be fairly easy thanks to the render target stack in KWin. Doing it this way would get rid of the ugly artifacts at window edges. The downside is that it introduces a requirement for maximum texture size to be at least the size of the virtual desktop (already imposed by the blur and backgroundcontrast effects). I'm planning to run this on an old Intel Pineview and I hope it would have enough juice to handle this.

  R108 KWin
