Description Richard Henderson 2004-05-20 21:03:30 EDT
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):

How reproducible:

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.

Comment 1 Dams 2004-09-27 15:45:16 EDT
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 15:59:45 EDT
Richard, are you using a translucent background?

Dams, there was a vte scrolling bug in fc3t2 that has been fixed in
Comment 3 Richard Henderson 2004-09-27 16:16:56 EDT
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 06:20:08 EDT
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.
