terminal bell causes wallpaper to flicker (or redraw, adding a noticable delay)

[Marques Johansson]

When using tab-completion, or otherwise triggering the terminal bell, the wallpaper switches to white and is then forced to redraw. This occurs with every beep and adds a substantial set of delays for someone who is tab-happy.

By disabling the terminal bell in gnome-terminal, this behavior is eliminated.

I found this setting "checked" in gconf:
/apps/compiz/plugins/fade/screen0/options/fullscreen_visual_bell

I disabled that setting (and re-enabled the terminal bell in gnome-terminal) and the problem went away, but I'm using metacity (because i865 will fail from compiz to metacity) so something else is honoring that setting and it is not obvious where I should go to disabled this.

I am currently using the most up-to-date Jaunty:

gnome-terminal 2.25.5-0ubuntu2
metacity: 1:2.25.144-0ubuntu1
compiz: 1:0.7.9+git20090211-0ubuntu4
xserver-xorg-video-intel: 2:2.6.1-1ubuntu2
xserver-xorg: 1:7.4~5ubuntu12

I don't see anything related in the ~/.xsession-errors or gdm/:0.log files.

The compiz setting hasn't corrected the problem. The correction must have come from changing my profile "terminal bell" setting in an open gnome-terminal tab. It seems like the setting isn't exactly sticky and other tabs (and new tabs or gnome-terminal windows) using the same profile aren't affected by the setting change.

I will assume that disabling terminal bell for all of my profiles and closing all of my gnome-terminal windows
will correct the matter, but that seems extreme.

This means that I am getting a full-screen bell for unknown reasons.

Now I've also seen the flicker just from opening or repositioning a gnome-terminal.

I am using the solid background, not the transparent background option, so that should not be the cause.

This means I am getting a wallpaper refresh for unknown reasons, but it seems strongly tied to the actions of gnome-terminal.

thanks for the report, could you send this upstream to bugzilla.gnome.org since you're having the issue? i cannot reproduce that behavior here, for forwarding instructions please have a look to https://wiki.ubuntu.com/Bugs/Upstream/GNOME ; leaving an upstream task open. thanks in advance.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Thanks in advance.

I have since updated to Karmic and can no longer reproduce the problem.

awesome, marking this as fixed then, thanks for the feedback.
