I used default KWin setup with OpenGL compositing. I modified Konsole and panels with transparency. But the output was like nondeterministic. Sometimes there was no transparency at all and sometimes very crispy, rarely it made transparent effect but I was unable to find what corrected the behavior. Later I tried other Scale methods and other Rendering backend and Xrender finally gave desired effect. Any idea how to make OpenGL work in KWin
