      If StageStyle.TRANSPARENT is used for a Stage instead of StageStyle.UNDECORATED then the CPU usage increases heavily.

      On my computer:
      JavaFxStageUndecoratedPerformanceOk.java has a CPU usage average of about 2%
      JavaFxStageTransparentPerformanceProblem.java has a CPU usage average of about 12% (+ 600%)

          2 kB
        2. JavaFxStageUndecoratedPerformanceOk.java
          2 kB
