Subject: Focus deadlock

I’m running an application on a Linux x86_64 machine which opens several windows for user input and data display. It runs fine unless I have an EPICS areadetector IOC running in the background, in which case I get a “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?
