Default gnome-terminal refresh problems

I'm having refresh problems within gnome-terminal with 177.68 beta on a nvidia 8400GS under Ubuntu 8.04.

Here is my xorg.conf.
Code:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 1.0  (buildmeister@builder57)  Tue Aug 19 21:13:45 PDT 2008

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

Well, firstly you should post a bug report. I'm guessing you followed the performance sticky and have this issue with InitialPixmapPlacement=2 and GlyphCache=1. Have you tried other IPP settings? Are you using transparency in the terminal (theres an issue with urxvt and fake transparency iirc)?

Default Re: gnome-terminal refresh problems

FWIW, I had these same problems with 177.6[78] (my bug-report is in the "power management is busted" thread, but it's not like any of that matters, and I tried changing just about everything before giving up on the Beta). Since 90% of my use is in gnome-terminals, I had to revert back to 173.14.12 .

What'll happen is ncurses-based screen updates (i.e., kernel's "make menuconfig", "less"ing on a file) don't always show up unless you do a full redraw.

I have not tried other IPP settings. The terminals are transparent, but turning off transparencies has no effect.

Removing nvidia-settings -a InitialPixmapPlacement=2 -a GlyphCache=1 also has no effect.

Default Re: gnome-terminal refresh problems

Actually after some time refresh problems appeared...too bad

===========
There is a workaround for this, just just terminal from xfce4 It looks and behaves almost like the one from Gnome but doesn't seem to be affected by that bug.

Just remember about executing
nvidia-settings -a InitialPixmapPlacement=2 -a GlyphCache=1

in your .bashrc and it should work.
