Description Richard Henderson 2004-05-21 01:03:30 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040506

Description of problem:
Screen refresh after exposure events is shamefully slow.

Version-Release number of selected component (if applicable):
gnome-terminal-2.6.0-2

How reproducible:
Always

Steps to Reproduce:
Stack a couple of windows on top of a complex background:
(1) gnome-terminal full of text
(2) xterm full of text
(3) mozilla displaying something arbitrary.
Grab a fourth window and move it over the lot of them.
    

Actual Results:
Notice that the gnome-terminal refresh significantly lags the
movement of the fourth window -- by up to half of the window
width -- and nothing else does.  Notice that you can visibly
identify multiple exposure events in the uncovered gnome-terminal.

Expected Results:
Refresh faster than the eye can follow.

I think the situation is far worse on fc3t2 with
gnome-terminal(0:2.7.3-1).i386... it's quite a hell. Self-scrolling
text (cat /some/big/file) in gnome-terminal is also quite a pain...
will this ever get better one day ?


Comment 2 Ray Strode [halfline] 2004-09-27 19:59:45 UTC
Richard, are you using a translucent background?

Dams, there was a vte scrolling bug in fc3t2 that has been fixed in
Rawhide.

Comment 3 Richard Henderson 2004-09-27 20:16:56 UTC
Absolutely not.  First, I can't read such things.  Second, I realize
that would *have* to be slow.  I'm even using the same "fixed" font
that's default with xterm, hoping to avoid extra work for keen-o
rendered fonts.

Comment 4 Warren Togami 2005-09-11 10:20:08 UTC
Performance problems are not a priority for Fedora.  Fedora has no resources to
work on this.  Please complain about vte performance problems at the upstream
GNOME project and bugzilla.gnome.org.
