Text editor problems

[amhar]

Hello everyone
First off, i'd like to state that i am running Ubuntu MATE 18.04 on my desktop without any problem.

I decided to build a new Premiership football league table using the 'Pluma' text editor. But the pluma text editor would use black squares on the end of each HTML5 tag which i didn't like and because
i didn't know how to remove them (the black squares), i decided to uninstall pluma and install Gedit instead. But whilst trying to use gedit it keeps on stalling. I can type a letter or an icon
and it won't appear for at least 10 seconds or more and sometimes it won't appear at all.

Whilst browsing the Internet or typing this topic there is no problem. The problem only occurs when i am trying to use the Gedit text editor. Could someone tell me what is going on here please
and how i might resolve this problem. Thanks all

Gedit is designed for the GNOME desktop environment. pluma is the fork of that same application which is reworked to function on the MATE desktop environment.
Gedit will still launch but will work incredibly slowly because it is pretty much constantly encountering errors and timeouts trying to access the gnome session manager. That cannot be fixed. (Or- rather, it was fixed- that is why pluma was created!)
