Extra Information Display Incorrectly

[zhangz]

When I moved my mouse on Process "chrome -type=gpu-broker",the monitor showed nothing but a black empty box. However,when I moved my mouse to other processes, the monitor showed the correct process command with arguments (like it will show "/sbin/init splash" when I moved the mouse on the process "systemd")
(sorry for my poor English
