gedit abnormally use high CPU

[Chia-Hao Hsu]

Gedit trigger an ubuntu high cpu consumption when the mouse is not in the windows of gedit.

 gnome-shell ate up 50 % of cpu, while Xorg consumed 20 % of cpu, gedit consumed 30 % of cpu. CPU is not able to cool down, when gedit is opened and the location of mouse is in other applications instead of gedit. If the situation goes on, system will hang.

  When Gedit is turned off in time, everything goes back to normal.

Update,

   I changed the configuration in Tweak Tool, change the "Focus Mode" from "mouse" to "Click". Afterthat, only when I do a click on the windows other than gedit induce the high cpu consumption. The operation did not show any noticeable error in system log file.

   Is there any suggestion, please?
