I’m running an application on a Linux x86_64 machine which opens several

“focus deadlock”, where focus shifts rapidly between two application
windows and the screen becomes unresponsive to keyboard or mouse input.
The problem occurs under Gnome but not KDE. Running KDE is an effective
fix, but it would be nice to get to the bottom of the problem. Can
anyone suggest what’s going on?
