Can you check if they are probably just moved to the background, i.e. they are 
created but the current window is kept as the "top most" one.

KWin, KDE's default window manager, has a feature called "focus stealing 
prevention", i.e. when a new window requests to be shown, it checks if the 
window actually "belongs" to the currently active one (e.g. a dialog of the 
same application) and otherwise creates it in the background, so input to the 
currently active windows does not get interrupted.

The application in question might not set the proper window manager hints to 
detect this association.

Cheers,
Kevin
