I'm using Qt4 for my application and when using multi-thread mode after a couple of beamOn I get the warning:
QPixmap: It is not safe to use pixmaps outside the GUI thread
then the visualization freeze.
Sometimes in the same condition I get the error:
Fatal IO error 11 (Resource temporarily unavailable) on X server :0.
Running in single-thread or in csh session using OGL the application works fine.
Is this a Geant4 issue or is a problem of my operating system/videocard driver?
Thank you and best regards
