Well, I have not identified the source of the problem yet.

But the symptoms are that InputEventFetcher>>primGetNextEvent: delivers 500-1000x more events than EventSensor>>primGetNextEvent: in MVC or Squeak 4.1 images deliver.

Could there be something else in PharoCore which interacts with the VM in unexpected ways?
In case that is relevant, the RoarVM uses X11 for the interface. (-headless has the same issues)
