Some tests to investigate and try to resolve an issue where deeper layered content within a scrollpane results in increasingly blurry text, buttons, etc.
If content is dynamically created and embedded within a series of scrollpanes, each layer becomes blurrier and blurrier.
For example, I created a test scenario (Test 04) where a ScrollPane wraps around a BorderPane that has a VBox at its center.
A button creates a new instance of this same view inside the VBox.
If you keep creating layers within layers using this view, they keep getting blurrier.
This gif illustrates the issue:
This is a gif illustrating the aplication of a fix for the behaviour:
