[panel] Invisible items in systray

It doesn't happen in the previous compiz-based unity. I'm running 10.10 Desktop.

Hello jminiesta, thanks for reporting that bug. I can reproduce it on my Ubuntu 10.10 installation.

It also affects gnome-do, but doesn't affect parcellite here.

Hi, I am still having this problem in unity-2d-3.8.4...

@pools: are you able to tell what icons are invisible? That would help a lot in identifying and fixing the issue.

just pidgin, skype, clementine and hptoolbox are OK

Confirmed, pidgin’s icon is there but invisible. This is with unity-2d 3.8.2-0ubuntu1.

Some information of what is happening with pidgin (2.7.11 currently in Natty): the first call to XGetImage in X11EmbedContainer::paintEvent(…) with dimensions 24×24 fails (as explained by the comment), but then the second call is also issued with dimensions 24×24, it logically fails too. This is because the size of the embedded window (d->attr.width × d->attr.height) is 200×200, not 16×16 as expected.

Interestingly, if the panel is killed and restarted while pidgin is running, the 16×16 icon now appears correctly. It looks like the size of the embedded window changes, from an initial value of 200×200 to 24×24, then 22×22, then 16×16. d->attr needs to be updated accordingly, probably in X11EmbedContainer::paintEvent(…).

Lowering the importance to medium, as in the specific case of pidgin (which seems to be the only problematic systray-embedded application) it is already integrating in the messaging menu, and the systray icon is never shown with the default settings anyway.

AGAIN pidgin icon system tray invisible. Please FIX Unity 3D / Unity 2D

Unity 2D 4.14 ppa daily.
Ubuntu 11.10
Pidgin 2.10
Whitelist Unity panel - test Pidgin, pidgin, all. nothing works :-(

Status changed to 'Confirmed' because the bug affects multiple users.

confirmed with unity-2d (5.8.0-0ubuntu1)

Hi guys, I'm trying on precise (12.04) and from what i can see Pidgin now appears under the message indicator and not as a separate indicator, can you confirm it works for you under precise (that will be released very soon)

I'm having this issue under 12.04 with the Pidgin icon being invisible. Although the Status works for me with Pidgin through the messaing menu, none of the other aspects of Pidgin are available through that menu for me.

Gremlyn1: Are you sure it's being invisible (look at the attachments in this bug)? I would say it is simply not there by design because it has a messaging indicator entry.

I can click where it should be and bring up the buddy list window, so yes I'd say it's invisible rather than missing entirely. It isn't properly integrating into the messaging menu either for me, as it doesn't give me any way to bring up the buddy list window...but that is a different bug I think.

I should also add that the icon WILL show up on the systray under Unity 3D, but does not under Unity 2D. Skype will show up on both with no problems. I manually enabled both icons to show up in the systray as I could not get either to integrate properly with the messaging menu (I would love for the messaging menu to take over on this, though).

Anyone else? Word on a potential fix to try?

I'm also experiencing this on both a 12.04 clean install and another machine upgraded from 11.10. The icon is invisible, but can be activated by left/right clicking the space where the icon should be. If you change the desktop theme to High Contrast, you can plainly see a dark gray square where the icon should be.

I have also noticed that doing a killall unity-2d-panel will cause the pidgin icon to display properly, but this does not always work, and the problem reoccurs if pidgin is stopped and restarted.

chuinker, thanks for the tip on the killall unity-2d-panel, I just did it and it worked to bring my icon back for now. The icon, however, does not look right. It appears to be too small - at least compared to what it used to look like under 10.04.

Can you guys post a screenshot of how it looks like once pidgin is in the panel? I have no way to put it there.

Also can you please post the output of doing these command in a terminal?

Interesting that between vadimo's screenshot and info and mine that 'indicator-status-provider-pidgin' is missing for his (and his icon is missing), but after running the killall unity-2d-panel, 'indicator-status-provider-pidgin' shows up.

I can't reproduce neither of the screenshots with neither of the setups :/

One more thing, what is the result of executing
dconf read /com/canonical/unity-2d/panel/applets
in a terminal?

Nothing.

michal@Asus:~$ dconf read /com/canonical/unity-2d/panel/applets
michal@Asus:~$

(My system is 12.04 LTS 64bit)

Then i have no clue since we seem to have the same package s installed and the same conf and i can't get your behaviour :_/

I have too removed these packages:
indicator-messages appmenu-gtk3 appmenu-gtk appmenu-qt firefox-globalmenu thunderbird-globalmenu

And in dconf-editor /desktop/unity/panel/systray-whitelist 'all'

Ahh, the whitelist thing helped!

Working on a fix

When can we expect this fix to make it to a stable release of unity-2d? I only ask because if it has been included in a recent release, then it is still not working.

I added pigin to the whitelist
gsettings set com.canonical.Unity.Panel systray-whitelist "['JavaEmbeddedFrame', 'Mumble', 'Wine', 'Skype', 'hp-systray', 'pidgin']"

Pidgin is in the panel, but it is invisible.
How can I fix that?

Hi,
I think I found a solution. The file "prefs.xml" in the .purple folder caused this bug. I deleted the file and now I have the pidgin messenger under the letter box in the unity panel. :)

I used the pidgin profile under windows once. Maybe the this caused the bug in unity?

Regards,
asgard2

Should this fix has made its way to the general public yet? My system still has this problem (12.04).

@gremlyn1: if you still have this bug, and none of the suggestions above work (i.e. in case pidgin is to blame), please reopen this bug.

Note that it's unlikely to be fixed however: unity-2d is not being worked on any more, and only security fixes will be considered. Apologies

Hi Gerry, thanks for the quick reply. I had forgotten than unity-2d was dropped in 12.10. I saw that a fix was committed for this bug, though it seems to be in v5.14 and currently my system has v5.12. Will 5.14 still be released? If so, I'll wait for that to drop and see if it is fixed before reopening. If not, is there any way I can get a patch of the committed fix to apply?
