Description of problem:
Screen refresh after exposure events is shamefully slow.
Version-Release number of selected component (if applicable):
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.
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.
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 ?
Richard, are you using a translucent background?
Dams, there was a vte scrolling bug in fc3t2 that has been fixed in
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
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.
