Hi, Since 26-ea+15, there may be a "bug" with TableView which appears to be rendering duplicated nodes.
I first noticed this when using ControlFX's TableRowExpanderColumn ( https://controlsfx.github.io/javadoc/11.2.2/org.controlsfx.controls/org/controlsfx/control/table/TableRowExpanderColumn.html), which has been working as expected for several years, right up until 26-ea+15. This column just provides a simple way to allow expansion of table rows. I have created a gist consisting of a single runnable class. It's quite small, and no dependencies are required (minimal ControlsFX code copied into it): https://gist.github.com/credmond/57ed65a20c1b4d1cf0272a71642077b0 Run this on 26-ea+15, and you'll see the issue re: duplicated rendering; run it on anything older, and there's no issue. If I had to guess, I'd say this issue is related to this commit (8359599): https://github.com/openjdk/jfx/commit/02756a810c54c4068505eca6d43c1ba2a136e04e The application starts out like this on all versions, there's three rows (number of rows is irrelevant): [image: image.png] Click the +'s and -'s more than once. 26-ea+15 "bug"; notice the duplications that appear just by clicking the + / -'s a couple of times: [image: image.png] 26-ea+14 (and previous) expected / normal behaviour: [image: image.png] Kind Regards, *Cormac Redmond*
