[ubuntu-mono] [Bug 403135] Re: Notification area icon wrongly rendered/uses bg_color as a background (multiple apps)

[Boris Dalstein]

In my case :
Lucid Lynx 32bits, default theme, nVidia card with Xinerama enabled : all (as far as I know) apps in the notification-area have a white background. (If Xinerama is disabled, the bug disappear in my configuration...)

I've tried to fix this by modifying the source code of gnome-panel (see
attachment) : I commented out things in applets>notification-area>na-
tray-child.c>na_tray_child_realize(GtkWidget *widget) in order to always
use the default "alpha drawing mode" (it is said that "the icon will sit
on top of an ugly gray box"). This worked for me, and for other people.
See http://ubuntuforums.org/showthread.php?t=1427968&page=5 post #48
(I'm seb_42) for more information.

However, in my configuration, this fix seems only to work for the
default theme. So it's clearly not a clean solution, but I thought I had
to post my "modifications" here, in case it can help.

** Attachment added: "commented source code (and binary for 10.04 32bits) that work for the default theme of Lucid"

Bug description:
The following bug may possibly depend on my setup, if so just tell me how to check this. I am using banshee 1.4.3-5 (in ubuntu karmic) and its notification area icon has a black background, unlike other applets that have a transparent background.

I attach a screenshot.

This bug is noticed when:
a) Themes set a background image in the gtkrc
b) If users set a custom image for the panel from Panel Properties > Background > Background Image

***This bug affects all themes , but has become easier to notice since the default light-themes use a background image.***

Also , see , comment #99 , might be a regression in gnome-panel since Karmic release.
