画面の右端にマウスを移動すると、右端に入ると垂直位置に関係なく、画面の右端の上から約25％下のポイントにジャンプします。
その後、Eclipseはコンテキストメニューが間違った場所（通常はカーソルの左側）に表示される奇妙な動作を発見しました。 Eclipseを再起動した後、Eclipseは問題がなくなり、最初の画面の右端に移動したときに再び表示されました。
私のシステムはMageia 8、Plasmaデスクトップ、Breezeテーマ、Linux 5.10.41、AMD64（Ryzen Threadripper 3960X 24コアプロセッサ）、2つのNVIDIA GPU（GeForce RTX 2080 SUPER）を搭載し、4kモニタに接続されています。
マウスジャンプは、Eclipseを実行するかどうかにかかわらず常に発生します。

この問題の原因は、xorg.conf が 2 つの画面で構成されていますが、モニターは 1 つだけが接続されているためです。
これは私のオリジナルのxorg.confです。

Screenセクションの2番目の部分をコメントアウトし、ServerLayout最後に2番目の部分の定義をコメントアウトすると、問題が解決されます（再起動後）。Screenマウスはエッジの周りにジャンプしなくなり、Eclipseコンテキストメニューは常にカーソルの下に表示されます。
