%localappdata%\Logitech\Logitech Gaming Software\settings.json

在最后一个括号前添加

, "notification" :    {     "showDpiChangeToastNotify" : false,     "showProfileChangeToastNotify" : false   }

保存退出，然后把settings.json设置成只读

如图：

     To anyone that stumbles with this you can disable the notifications  by editing the file located at: `%localappdata%\Logitech\Logitech Gaming  Software\settings.json`  

     and adding this before the last }:  

, "notification" :    {     "showDpiChangeToastNotify" : false,     "showProfileChangeToastNotify" : false   }

Set the file to read-only!
