Version: (using KDE 4.2.0) OS: Linux Installed from: Ubuntu Packages I have set Window Behavior, focus, policy "Click to focus" and Window actions, Inactive Inner Window, Left Button "Activate, Raise & pass Click". At first it works fine. Then I make some changes in the configuration and when I change Desktop -> Desktop Effect -> Advanced -> XRender Options and activate "Smooth scaling", then clicking inside any window (Except Firefox!) passes the click but does not activate or raise. Deactivating "Smooth scaling" does not solve the problem.
Can you reproduce this bug on a recent version of KDE eg. 4.5? It seems to work alright for me.
Obviously outdated, no reply since 15 months and the report is far too unsharp to make anything out of it (and i use xrender on one of my systems everyday)
