我在 14 英寸笔记本电脑上运行 xpra 客户端，在 15 英寸笔记本电脑上运行 xpra 服务器。 14英寸笔记本电脑上的xpra客户端窗口仅部分显示15英寸笔记本电脑的屏幕（靠近底部的部分和靠近右侧的部分被切除）。下面的屏幕截图显示了 14 英寸笔记本电脑的屏幕，其中包含 xpra 客户端窗口。
两台笔记本电脑都运行 Lubuntu 18.04。
远程xpra版本以及屏幕尺寸和分辨率为：
$ xpra --version
xpra v3.0.8-r25889
$ xdpyinfo | grep dimensions
dimensions: 1920x1080 pixels (508x285 millimeters)
本地xpra版本以及屏幕尺寸和分辨率为：
$ xpra --version
xpra v3.0.8-r25889
$ xdpyinfo | grep dimensions
dimensions: 1440x900 pixels (381x238 millimeters)
这是我运行的连接命令。我是否需要在命令中提供更多信息来解决问题？
