I am a new user with Ubuntu, so there may be some misconfiguration involved that I am not aware of, nor have a clue of fixing. I would ask a support question if I could think of some way to ask it so that it doesn't sound like a bug report. I find it difficult to imagine that a mature program like gedit itself is buggy. I am using 14.10 pretty much as it came.
I can view and type quite a bit without problem, but when I begin to cut and paste gedit begins to act flaky. The first symptom is an irratic cursor. It will effectively dissappear. Actually, it acts like it is too busy doing something else to paint the cursor. When I move the cursor with the mouse, I may see it occaisionally flash onto the screen. Editting may continue for a while, but the application's response gets progressively slower. Eventually the application terminates abnormally, and I loose my edit.
Another symptom that occurs is my CPU fan kicks into high gear, like it is compensating for a heavy workload.
When the problem occurs I can restore gedit to working order by saving the file I am editing, or by switching focus to another window and then back.
I've used the browser, compiler, word processor, and terminal without incident.
