[compiz] applets with Dock type window leave shadow

[darthanubis]

Binary package hint: compiz

Steps to reproduce this sub-bug:

1. Add GNOME Invest applet to a panel.
2. In its preferences, add some stock symbols, like GOOG, AMD, INTC (thanks darthanubis in #ubuntu+1 for these sample symbols).
3. Close the preferences.
4. Click the applet.

If you have a window over the invest applet, or maximised, you won't see a shadow in compiz. Minimise all windows, however, and you'll see the shadow. Now click the Invest applet button again to dismiss it and only the shadow stays.

i have this bug when using the invest applet or the dictionary applet. these are panel applets. when they are opened and closed a shadow reamins on the destop, overlaying icons etc. only happens with compiz, not metacity.

to reproduce:

use compiz
add invest or dictionary applet to panel
click widget to open the applet window
click widget to close the applet window
observe shadow.

screenshot attached

regards,
ex-oficio

[ex-oficio (wilkinson-luke)]

i should say, im using nvidia 185.18.36 and 64bit ubuntu.

[darthanubis (darthanubis)]

Thank you, because I thought this bug would be dismissed as just one person having this issue. I have this issue on two of my 64bit, Nvidia, 9.10 systems.

[ex-oficio (wilkinson-luke)]

i believe this is a duplicate of this bug:

[Travis Watkins (amaranth)]

I've added gnome-applets and gnome-utils tasks to this bug because these applets should not be using the dock type for their windows as that causes problems with metacity compositing as well (but just a bad effect instead of a lingering shadow).

Even after fixing this bug in compiz these two should be fixed to use a different window type.

[Travis Watkins (amaranth)]

Here is the test case from bug 458385 to trigger this bug in compiz.

[ssbastos (bastos-sergio)]

This problem affects me too... I thought the problem was related to the nvidia graphics card that I was using, but I recently installed ubuntu 9.10 x64 on a laptop with an ATI Radeon card and the problem is still there...

[Twisted Lucidity (lucidlytwisted)]

Just worked around this by changing the "Show windows" rule in "Window decorations" from "CompizConfig Settings Manager" to "(any) & !(type=Dock)".

Seems to work OK and is similar to what needs to be done to fix seamless-RDP.

Hello everybody. Bravo for helping the software we all freely share. That's ubuntu spirit.

I think that this certain bug report is more generalized than it should be. I'll explain myself right away. The problem does not affect every window which is type=Dock. For example the clock applet as also the gnome panel its self are dock type windows but you can hide them without any problem of remaining shadow. This is the reason for having a separate fix for the bug #428783 which was about the clock. The same way, the dictionary applet requires a different, separate fix.

@ roadSurfer: You suggested a nice work around. I'll make a little correction. Setting the "Shadow windows" rule to "(any) & !(type=Dock)" also removes the shadow from the panel which is not very nice (though it's not a big problem). I suggest to isolate just the problematic applet windows setting the rule to "(any) & !(class=Gnome-dictionary-applet) & !(class=Invest-applet)".

I think it's clear that the bug does not affect every dock type window and as so I think that the summary should refer only to the invest applet.

[RodGer (rodger)]

I also confirmed that this bug affects me too. Ah! and a little correction of my comment above: "Bravo for helping
++improve++ the..."

[darthanubis (darthanubis)]

I don't know how or when this got resolve for me. But I no longer have this issue.

[Travis Watkins (amaranth)]

If you look at the test case you can see it affects every Dock type window that is hidden rather than destroyed. The clock was fixed by making destroyed windows get their shadow cleaned up properly, this one apparently needs hidden windows to get their shadow cleaned up properly. It is a rather general problem though.

[RodGer (rodger)]

Gnome panel is also a dock type window that is hidden (use show hide buttons or auto-hide) but it has no problem. Is there any other (than invest and dictionary applet) example of a dock type window that is hidden rather than destroyed?

Sorry but I'm learning.How can you see if a dock type window is hidden or destroyed? Where can I find the source code of compiz (in what prog. language it is written?) ? Which way are the dock type windows defined in compiz source code?

[Travis Watkins (amaranth)]

Actually the panel moves and resizes, it doesn't actually hide. Explaining how compiz works would take longer than it'll take to fix this problem. :)

[Norman Perelson (simplr)]

Nobody has mentioned the Drawer applet. It affects that too.

[RodGer (rodger)]

Indeed, it affects the drawer applet to. When you close the drawer the shadow remains remains until I click on the desktop. The main problem is solved but not totally. Also, the test case, Travis Watkins posted, still gives the same result: the little window lives a shadow that won't go away no matter what you do.

The bug is partially fixed. I don't know if we should open the bug again. If anybody still has a problem, after updating his system, please let us know.

[RodGer (rodger)]

Sorry for my mistakes in the previous comment. Here it is corrected:

[Travis Watkins (amaranth)]

Both the test case and the drawer work perfectly on my up-to-date lucid system.

[sirald66 (sirald66)]

Jaunty (9.04) seemed to be fine, where Karmic (9.10) introduced the problem.

Why is the solution in Lucid (10.04) and not applied to Karmic?

[For those with the touchpad mouse jump/lock problem, I'm told the solution is also in Lucid. This development cycle is starting to remind me of Microsoft -- where before the bugs are crushed, new features+bugs are introduced; a never ending story.]

[Sebastien Bacher (seb128)]

the applet is deprecated in GNOME3 and oneiric, closing the bug
