我有一个预装了 LibreOffice 的 Ubuntu 17.10 安装。当我打开 LibreOffice Writer 时，它会在左侧的任务栏（即应用程序停靠栏）中显示一个空白图标（第 1 张屏幕截图）。如果我将应用程序从全屏应用程序启动器拖放到停靠栏（即添加到收藏夹）并启动应用程序，它仍然会打开一个空白图标（第 2 张屏幕截图）。事实上，任何 LibreOffice 应用程序都会打开相同的空白图标，无论是 Writer、Impress 还是 Calc。LibreOffice 套件本身也会在应用程序启动器中显示为一个空白图标（第 3 张屏幕截图）。
这不会以任何方式、形式影响应用程序的性能，但这个缺陷让我非常烦恼，而且当你同时打开多个 LibreOffice 应用程序时，它也使得区分它们变得更加困难。
希望有人能提出一些技巧来解决这个问题！谢谢
