Enclosing class:

FlatPopupFactory

private class FlatPopupFactory.NonFlashingPopup
extends javax.swing.Popup

Fixes popup background flashing effect when using dark theme on light platform theme, where the light popup background is shown for a fraction of a second before the dark popup content is shown. This is fixed by setting popup background to content background.

Defers hiding of heavy weight popup window for an event cycle, which allows reusing popup window to avoid flicker when "moving" popup.
