Public bug reported:
First, sorry if this bug is not vte related, maybe it's more gtk than
vte? I can only reproduce this problem with gnome-terminal and
xfce4-terminal but not with xterm for example. The common thing between
xfce4-terminal and gnome-terminal is using libvte as well, that's the
reason I try to bugreport here. If I was wrong, please move my report to
the right place, thanks!
The bug now: I'm using multiple workspaces ("desktops") under
gnome/metacity with Ubuntu maverick 32bit OS. I have this problem on two
machines, but it's hard to tell when, it seems if the problem begins it
remains, but I don't know what can cause the beginning of the problem.
If I change workspaces, and I switch onto a workspace which have a
"large enough" terminal window (not a standard 80x24 but a larger, like
130x90 or even full screen) the change is _very_ slow, sometimes my X
session is frozen for 4-5 seconds! Within that time I see the old
workspace (but as frozen, though I can move the mouse cursor) before the
new appears. It seems I can have even dozens of terminal windows without
a problem, if none of them is "large enough" window to trigger the
problem.
This is a very annoying problem for me, because I'm using terminals and
multiple workspaces quite heavily, but that delay is awful especially if
I only want a quick look at a terminal then I would switch back to
another one on another workspace. As I've already told, it seems xterm
is not affected only gtk/vte based terminals. I am not using compiz at
all (though I've activated the internal compositing support of metacity
wia gconf). The problem exists even with "semi transparent" and non-
transparent (static black) background configured for gnome-terminal.
