Hi Xing,

   You have the latest CentOS 7 up-to-date version.

 This bug is related with nautils and other Qt objects within your

GUI environment. You could wait for their upcoming patch, because of

this patch https://bugzilla.redhat.com/show_bug.cgi?id=1594177

 If you want to do some minimal action to work around this issue, I

recommend to install "Mate Desktop" instead of Qt or Gnome.

   sudo yum install epel-release -y
   sudo yum groupinstall "Mate Desktop" -y

   sudo reboot

 In the login terminal, you can see the small option symbol below the

login window (*), you can switch from gnome classic or 3 to Mate.

 Please try to do this first, and let me know. In case, this quick

solution doesn't work with your environment because of your

configuration. I hope your system has the default and native repository

configuration.

   HTH,
   Han
