Description
FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
Event coalescing/optimization happens on the EventQueue, while the EventQueue processes the payload. Under single threaded AWT/FX mode, the EventQueue dispatches events without processing them, therefore event coalescing is not happening, causing event storms (mouse move, paint, etc) on the JavaFX thread.


REPRODUCIBILITY :
This bug can be reproduced always.
Comments
This might be a JavaFX bug rather than an AWT bug.
