I tried now the following:

1) override_redirect set to True instead of False => broken
2) KWin compositor with OpenGL 2.0 (what I had so far) => broken
3) KWin compositor with OpenGL 3.1 (didn't see that being added) => broken
4) KWin compositor with XRender => broken
5) KWin compositor disabled => works flawless
