Mathematica 设定其文档中心作为一个标志性的窗口，根据xprop。我认为这种状态可能是使该窗口成为僵尸窗口的罪魁祸首，无法通过窗口管理器上的鼠标聚焦。我可以使用某些 X 工具将窗口状态更改为正常吗？
这是以下的输出xprop：
_NET_WM_DESKTOP(CARDINAL) = 3
_NET_WM_SYNC_REQUEST_COUNTER(CARDINAL) = 25191353
_NET_WM_USER_TIME(CARDINAL) = 46824074
_NET_WM_NAME(UTF8_STRING) = "Mathematica - Wolfram Mathematica"
_NET_WM_ICON(CARDINAL) = Icon (31 x 32):
