Bug Description

Binary package hint: compiz

Hello,

I'm part of the Cairo-Dock team. Cairo-Dock is (more than :) ) a dock using Cairo/OpenGL backend. It needs a composite support and it worked very well until this last month on Ubuntu Karmic : some flashes appear (rarely) when the window used by Cairo-Dock is resized. In fact Cairo-Dock resizes its window when the dock is active.

I saw this bug last month (~28 Aug) and it seems that it's not a bug due to Cairo-Dock. I haven't any problem on Jaunty and I use Karmic from the beginning. I've also tested with a previous version of Cairo-Dock and the problem is the same. The problem is also present with the last release of Compiz (0.8.3+git20090917-0ubuntu1).
I guess it's due to the 0.8.2-0ubuntu16 release. You can look at the diff file : http://launchpadlibrarian.net/30801086/compiz_1:0.8.2-0ubuntu15_1:0.8.2-0ubuntu16.diff.gz

For more informations about Cairo-Dock and its installation, look there : http://www.cairo-dock.org/ww_page.php or https://edge.launchpad.net/cairo-dock

Thanks for your help and for your great project !

So when you use the ubuntu15 package packages this doesn't happen?

I'm almost sure.

I see that I can download old deb packages in this page : https://edge.launchpad.net/ubuntu/+source/compiz/1:0.8.2-0ubuntu15
I can test these packages tonight if you want.

I'm now sure !
I downgraded to the version 0.8.2-ubuntu15 and now I don't have these flashes !
I have installed these packages : compiz_0.8.2-0ubuntu15_all.deb, compiz-core_0.8.2-0ubuntu15_amd64.deb, compiz-fusion-plugins-extra_0.8.2-0ubuntu4_amd64.deb, compiz-fusion-plugins-main_0.8.2-0ubuntu5_amd64.deb, compiz-fusion-plugins-unsupported_0.8.2-1ubuntu1_amd64.deb, compiz-gnome_0.8.2-0ubuntu15_amd64.deb, compiz-plugins_0.8.2-0ubuntu15_amd64.deb, compiz-wrapper_0.8.2-0ubuntu15_amd64.deb, libcompizconfig0_0.8.2-0ubuntu2_amd64.deb, libdecoration0_0.8.2-0ubuntu15_amd64.deb

For me the bug is due to this rev 0.8.2-ubuntu16 but I'm not a specialist like you ;)

Alright, it looks like that patch is the problem then. However, I see no way to fix the problem without reverting the patch. Since cairo-dock is not the default and not used by many users this won't happen for karmic. For lucid I'll see if there is another fix we can figure out.

I confirm the bug, I didn't have it before I update to Karmic, with the same version of Cairo-Dock.
please fix it, it's very ennoying.

PS : I don't think it's a safe attitude to let bugs just because it doesn't affect "many users"
Did you know that Cairo-Dock has at least 50000 users ?
Such a bug should certainly not be released in an official version of Ubuntu !

Travis Watkins (amaranth) wrote :

And Ubuntu has at least 4 million users. 50,000 is not so much compared to that. It doesn't happen with gnome-do's docky mode either. It's not worth giving this small group a good experience when it would give the majority a bad experience. If you can figure out a way to do both we'll do that.

This bug affects me too. I agree with Fabounet and Matthieu : this bug is annoying and should be fixed even if you don't use Cairo-Dock

Fabounet (fabounet03) wrote :

Travis this is not the question, if the patch leads to a regression, it should be postponed until it is corrected.
This would be a sane attitude.
Or maybe someone can correct it shortly ? It was working well before, so the problem should not be that big.

As said Fabounet, this patch is a regression for some comportments (the resizing of windows). There is a problem with Cairo-Dock but maybe with plenty others apps which have not been already tested on Karmic...

> And Ubuntu has at least 4 million users. 50,000 is not so much compared to that
This is typically an answer of Windows dev...

I hope that you will think to all people :)

As I said, I'm looking at the greater good here. If the patch is shown to affect programs used by more people it will be reverted otherwise we'll have to figure out a way to fix the patch or fix cairo-dock. I most likely will not have time to do this before the karmic release.

I confirm this bug on updated Debian squeeze. However, I use Compiz 0.7.8 (because it seems Compiz 0.8.2 has a bug in its scale add-on).

Oh, pardon me! I was sent here from the Cairo-dock bug report and didn't read the page carefully. In fact, my using Compiz 0.7.8 and having the same problem with Cairo-Dock resizing may prove that this is not a Compiz bug.

@ Tsu Jan : this bug was also present in this 'old' release of Compiz but solved after (until the application of a patch in this 0.8.2-0ubuntu16 release).
