Title:
  gnome terminal becomes very slow after a few days of intense usage

Status in “gnome-terminal” package in Ubuntu:
  New

Bug description:
  (My work requires intense usage of terminals. Hence I am using Gnome
  terminal. Typically I have opened about 5 terminal windows which
  include 15-20 tabs all together. Scrolling is enabled, too, up to 1024
  lines.)

  The terminals become very sluggish after they are opened a few days
  (4-6). I.e. switching from one terminal window to other is very slow.
  Switching between tabs also becomes slower. Switching from other
  application to a gnome terminal is also very slow. The "intense usage"
  of the terminals is that I am using vim to view files.  I often use
  also tail to see last say 60 lines of files. Etc.

  The bug affects also terminator. The only "help" is to reboot
  computer. This is however very annoying because I need my workstation
  to be running almost permanently.  (I have many ssh network
  connections opened.) Typically I need uptimes about one month. Ubuntu
  11.04 allows me for uptimes only up to few days. It might look that I
  could use xterm instead. However xterm does not support many things I
  need (e.g. multitabs, some encodings etc.)

  This buggy behaviour was not present on older ubuntu releases. 
  I had reported essentially this same bug in the past. However it has expired. See bug 784519. That time I wrote something in the sense that the slowly responding terminals were occurring after heavy computational load. Now I know that the sluggish responses start to occur also without heavy load.

  I am reopening this bug because it is really very annoying and slows
  down work of users like me. Do you think that terminals in Kubuntu
  11.04 (or better 11.10) are free of this bug? Or would you better
  suggest to use Xubuntu?

  Finally, I am using an NVidia GeForce 9800 GT graphics card driven by
  270.41.06 NVidia driver. My desktop is Ubuntu classic. No visual
  effect. (People were saying that the bug might have something to do
  also with incorrect memory management in GPU.)
