If Parent has no background, is cached (Node#setCache(true)), and has LCD Text inside, then the Text will fail to render LCD.
In the NG layer that maps to NGRegion to renders to cache (NGNode#renderCached).
When this NGRegion has a NGText descent, then LCD sampling fails.
If you stick another NGRegion with a background between the cached NGRegion and NGText then it all works.

Note that is a common in Controls (as all controls are cached).

Testcase:
void start(Stage stage) {
    Text text1 = new Text("text1");
    text1.setFontSmoothingType(FontSmoothingType.LCD);
    Text text2 = new Text("text2");
    text2.setFontSmoothingType(FontSmoothingType.LCD);
    StackPane label1 = new StackPane(text1);
    StackPane label2 = new StackPane(text2);
    label2.setBackground(new Background(new BackgroundFill(Color.web("#EEEEEE"),
                                                           null, null)));

    Pane panel = new VBox(label1, label2);
    Pane scrollPane = new Pane(panel);
    scrollPane.setCache(true);//kills LCD for text1, text2 is okay as label2 has a background set
    Scene s = new Scene(scrollPane, 200, 200);
    stage.setScene(s);
    stage.show();
