Bug 209774

Version:            (using KDE 4.3.1)
OS:                Linux
Installed from:    Fedora RPMs

When I close a window, the input focus is not restored to the window that kwin decorates as the new active window. 

Scenario:
- open a konsole
- from konsole, start kate
- close kate: kwin decorates konsole as active - as expected - but keystrokes result in nothing.

However, ALT+F2 ALT+TAB ... still work. Indeed, switching back and forth to another application restores the input focus. If no other application is open, opening a new kate with ALT+F2, then switching back to konsole with ALT+TAB also restores the keyboard input.

The problem is not specifically related to konsole or kate: I observe the same behavior with whatever KDE application I've tried till now, namely konqueror and kmail. If I open konqueror, type in something in the URL input, then close konqueror, the keyboard is lost. However, if I open konqueror and just close it (without typing in an input field), there is no problem, and the focus is correctly restored.

This might be related to the X server, but it's definitely specific to KDE (or maybe QT). I could not find any other application where closing does the same thing.


My install comes from a fedora 11 x86_64, with updates:
  kdebase-4.3.1-2.fc11.x86_64
  xorg-x11-server-common-1.6.4-0.1.fc11.x86_64

I've used X drivers NV and VESA, both with the same result.

Yours for further investigation.
