私はで実験してきTreeTableViewましたJDK 8。プログラムを起動して機能させた後、スクロールすると行が空白になるという問題に気付きました。更新時にセルの可視性をリセットすることから、更新時に再描画されることを期待して、列の可視性をリセットすることまで、すべてを試しました。これは、ツリー テーブル ビューをスクロールすると行が空白になることを示すために作成したテスト アプレットですが、テーブル ビューの場合はそうではありません。

誰かがこれの修正/解決策を知っていますか、それともこれは の既知のバグTreeTableViewですか?
編集：この例を使用してこれを試しました

行が欠落している/白く表示されているという同じ問題が引き続き発生します。
