--- Comment #4 from Henri Verbeet hverbeet@gmail.com 2012-10-02 07:48:32 CDT --- For what it's worth, I think these are mostly existing issues, that didn't affect you before because kwin sets the netwm maximized state on fullscreen windows. The original bug you described happens for me even before the commit in question. I'll see if I can reproduce the other issues you mentioned, but so far I haven't seen those.
