xpra：クライアントウィンドウには、サーバーホスト画面の一部のみが表示されます。

私は14インチのラップトップでxpraクライアントを実行し、15インチのラップトップでxpraサーバーを実行しています。 14インチノートブックのxpraクライアントウィンドウには、15インチノートブックの画面が部分的にのみ表示されます（下部の近くと右の近くの部分が切り捨てられます）。下のスクリーンショットは、xpraクライアントウィンドウを含む14インチノートパソコンの画面を示しています。

どちらのノートブックもLubuntu 18.04を実行しています。

リモートXpraバージョン、画面サイズ、解像度は次のとおりです。

$ xpra --version
xpra v3.0.8-r25889

$ xdpyinfo | grep dimensions
  dimensions:    1920x1080 pixels (508x285 millimeters)

ローカルxpraバージョンと画面サイズと解像度は次のとおりです。

$ xpra --version
xpra v3.0.8-r25889

$ xdpyinfo | grep dimensions
  dimensions:    1440x900 pixels (381x238 millimeters)

私が実行した接続コマンドです。問題を解決するには、コマンドに追加情報を提供する必要がありますか？
