[Mark Cocker <367372@xxxxxxxxxxxxxxxxxx>]

I am seeing this issue on a new install of Ubuntu 14.10 64-bit with
NVIDIA driver 331.89.

I get about 50% CPU on 8 cores just just editing a new (unsaved) text
document.  If I give focus to another window the CPU drops and the mouse
correctly shows, and I can then go back to gedit and things are fine for
a minute or so then CPU spikes again.

I do not see this issue with any other application.

Title:
  Gedit uses 100% of the CPU while editing files

Status in Light-Weight Text Editor for Gnome:
  New
Status in “gedit” package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: gedit

  Making changes to a file(typing or deleting characters) makes gedit consume 100% of the CPU power available.
  I noticed this since I've installed Ubuntu 9.04. 

  I was poking in the fonts setting under the appearance preferences and
  I thought I noticed a slight difference if I turn off all processing
  and make the font glyph render without subpixel rendering and hinting.
  However it is merely marginal. To make sure it was not the graphics
  drivers I switched from the ati drivers to vesa but that did not help
  at all.

  I am running on a 5 years old Dell Inspiron 5100 laptop with Radeon Mobility 7500(details in lspci-vvnn.log provided in link below), with 256MiB of RAM.
