Hi,

Our environment has a Debian based box attached to a large LCD panel for video output. User interaction is handled via an IR touch screen plated on that panel. Gnome Shell 3.8.4 is running as the window manager.

Steps to re-produce our so error:

1. Open an application which has a window (e.g. Firefox)
2. Start another application up (e.g. Nautilus)
3. Touch the title bar of the first application and move it around the screen.
4. End the touching event.
5. Now touch on the title bar of the second application.
6. Hold on and try to move it around the screen. But, in a weird way, the first application's window is sticked to the focus event.

To sum up, the focus does not pass to the next window over the title bar. We are able to interact with the next opened window. However, touching the title bar does not change the focus.

We are able to produce the same behaviour for all applications we run. We searched through the filed bugs but no match found for a similar report.

Is there any workaround about it? Otherwise is it a known bug?

Thanks.
