I found strange thing using
wmctrl utility to get window size by running
wmctrl -lG. I found, that size of gedit window is icnorrect. I equaled sizes of Terminal and gedit window, however
wmctrl showed different sizes for these windows.
I'm using Ubuntu 16.04 with xfce DE, however the same problem I noticed in Centos 7
Could you please explain why
wmctrl shows incorrect size of gedit window?
