Description of problem:
When in less or man, using PageUp will leave artifacts as it scrolls up. It is
also much slower than PageDown.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Use less or man to read something
2. Use PageDown to scroll down
3. Use PageUp to scroll up to see the difference
Actual Results: PageDown works, and PageUp causes artifacts until it reaches
the bottom of the page, and then refreshes. It is also slower.
Expected Results: PageUp should work like PageDown
Is this in a particular terminal type, or all types?
This is in gnome-terminal. I'll try some other terminals and see if it acts
This only affects gnome-terminal
This sounds an aweful lot like the bug I reported for Gnome-Terminal
in Redhat 9 (still hasn't been fixed in FC1):
I've just been noticing it in a different place: When I'm running
mutt under a screen session. I don't get the same problem when
I can provide more details if requested. I'd like to see this one
solved. It only happens under gnome-terminal. Others (xterm,
multi-gnome-terminal, etc.) work fine.
Still happens in FC2-test1
This may very well be the same problem i've been seeing - Here the
most convinsible app to show the problem is vim scrolling up/down in a
System uses 100% CPU X about 97% gnome-terminal about 3%. I know that
due to the nature of X it will often be blamed for high loads when
it's actually an app that's the problem - please let me know how to
split the results if required!
This actually looks an awful lot like this issue that's been discussed
on bugzilla.gnome.org a while ago! It does not look like there is a
please move bug to vte if you think this is correct!
Thanks for the link. I also see that Bug #85874 is similar, and Havoc
said that it was a vte problem, so I'll try to change it to vte.
for a more detailed description of the same problem.
http://bugzilla.gnome.org/show_bug.cgi?id=120401 claims this is fixed in
vte-0.11.14, which is now pushed into FC3, FC4 and FC5.
Seems to do the trick for me regarding the page-up lag in less at least...
gnome-terminal is still very slow compared to xterm and konsole...
in a maximized gnome-terminal try this:
time find /usr -print0
on my System it takes ~ 55 seconds to complete
in xterm and konsole, results for both is ~ 16-17 secs
