Problem reproduction:
Log into Gnome Desktop as normal user, open Gnome Terminal.
Text remnants on last line is seen for BOTH root AND normal user in
Gnome Terminal running:
[khoa@nile ~] /bin/vi /etc/passwd
[khoa@nile ~] /bin/vi -U NONE -u NONE /etc/passwd
[khoa@nile ~] /usr/bin/vim -U NONE -u NONE /etc/passwd
(or any large text file), then scroll downwards. The problem is
that when scrolling down, the last line displays let's say line 30,
then line 31, then line 32, etc... If line 30 has more text than
line 31 and 32, parts of line 30 remains on the last line when the
last line is displaying line 32.
Problem never occurs when run in text console window (ALT-F1) or
xterm.
The command:
[khoa@nile ~] /usr/bin/vim /etc/passwd
does NOT exhibit this problem, UNTIL :set noruler is entered
while editing the file. With :set noruler, the problem shows up.
Seems that vim does something with respect to screen redraw that
doesn't work properly with Gnome Terminal 2.14.0, and that
this is masked by the :set ruler feature. Drawing the ruler
eliminates this remnants on scrolling problem.
The issue with root or normal user was an unfortunate coincidence,
and has no direct bearing on the problem except that root normally
calls /bin/vi, which always has :set noruler.
This happens on a brand new Fedora FC5 installation, with latest
yum update as of 3/28/06.
Thanks
