I used gedit on Ubuntu for my everyday life. Previously it is fine, but some weeks ago a strange thing happens. It consumes high CPU. I disable all plugins, and monitor the CPU usage. You can see in screenshot below with its htop monitoring process.
What is the possible cause? I used 3.18 version, and I downgraded to Gedit 3.10 and the problem still persists. I change from lightdm to gdm3 (as the xorg used lightm), the problem also still persist.
The high CPU usually followed by xorg process, both consuming > 60 % each. Recently I just moved from synaptics to libinput, but I think it is not the cause. My machine is macbook pro, mid 2012.
I dive into system log and nothing strange.
Any helps will be appreciated.
