Compiz scale option corrupts minimized windows

[Joschi Poschi]

What happens:
1. I have open several maximized applications
2. I minimize one application
3. I scale and choose one of the maximized applications
4. I choose the minimized application from the launcher
5. The application's window (the one that was minimized) is somehow move up about 30 pixel and not integrated into the panel anymore but behind it.

[Alex Launi (alexlauni)]

Could you please attach a screenshot of the issue?

[Joschi Poschi (joschiposchi)]

Sure. I also measured the amount of pixels the windows are moved up, it's 24. By using the show desktop command I can correct that behaviour quite fast, but I don't think the observed behaviour isn't intended.
The arrows on the bottom show the elevation of the windows, in the upper part you can see the tab part of Firefox being hidden behind the panel as if moved there with Alt+Button1. Every window can be corrupted by the scale function while being minimized.

[Joschi Poschi (joschiposchi)]

What I just noticed is that everything in the corrupted windows seems to be in the right place and just the view is corrupted. As you can see in the image the cursor is much lower than the selected tab, in the place where the tab should actual be.

[Joschi Poschi (joschiposchi)]

Can I do anything further to help solving this problem?

[Joschi Poschi (joschiposchi)]

I still have this problem and I'm wondering why nobody else got it.
It's really annoying and if I had any programming/bug fixing skills I would do it myself.
So again my question: what can I do to get this fixed soon?

[jhfhlkjlj (fdsuufijjejejejej-deactivatedaccount)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. Compiz, in particular, is in heavy development and this bug may have been fixed in the development version of Ubuntu (12.04) if not on the current 11.10 release. If you are able, it would be of great help if you could confirm if the bug still exists by testing a livecd (available at http://cdimage.ubuntu.com/daily-live/current/). When you test it and it is still an issue, kindly upload the updated logs by running apport-collect <bug #> and any other logs that are relevant for this particular issue. Please keep in mind that the development version (12.04) is not suitable for daily use - please only use it for testing purposes.

Thank you for your help and patience.

[Joschi Poschi (joschiposchi)]

It's still persistent in Precise, but don't know how to exactly get the needed information. Could someone please tell me the exact terminal commands?

[jhfhlkjlj (fdsuufijjejejejej-deactivatedaccount)]

Hi. I don't doubt that you have this issue but I can't reproduce this for the life of me.

If you could run 'apport-collect 875709' in the terminal, it would be of great help. Perhaps even a small screencast of the bug in action (on Precise would be best, and I'd recommend the program Kazam as recordmydesktop has been badly broken recently).

Thanks for your patience.

Great. Now would you be so kind as to record the behavior? :)

[Joschi Poschi (joschiposchi)]

In the video you can see the described behaviour:
after minimizing a program and using the 'Show Dekstop' command of Compiz to minimize and maximze again all open windows the before minimized program after getting it back via the launcher is moved up some pixels.
http://dl.dropbox.com/u/24022880/Compiz.webm

[Joschi Poschi (joschiposchi)]

So what do you think of this bug?
Seems to be not only the 'Scale' plugin as in the bug description (I remembered it wrong before recording the movie) but also the 'Show Desktop' funktion (that I linked to the upper right corner).
I think Compiz is forgetting/falsely remembering the position of the first minimized window while scaling or minimizing/maximizing the others.

[Joschi Poschi (joschiposchi)]

Anything else you need?
Bug is still persistent on both of my laptops with all the latest Precise updates.

[jhfhlkjlj (fdsuufijjejejejej-deactivatedaccount)]

What we need are more people that can reproduce this bug :). Again, I've tried multiple times and I can't reproduce this - which is odd, as I'd imagine the same behavior would occur on any machine. Unfortunately, until someone working on compiz can also reproduce and find the bug we'll just have to wait.

Thanks for your patience.

[jhfhlkjlj (fdsuufijjejejejej-deactivatedaccount)]

Upon looking at your video again, I'm wondering: Do you have two monitors set up? This looks like a bad interaction between two resolutions. I've also noticed that when you minimized VLC, the software center does not have focus. This does not happen on either Oneiric or Precise to me as well.

[jhfhlkjlj (fdsuufijjejejejej-deactivatedaccount)]

Also! I see that mouse cursor of yours is not a gnome mouse but rather a Windows mouse. Are you running this in a virtual machine?

[Joschi Poschi (joschiposchi)]

No this is just the ubutaero mouse theme from gnome look.
I don't use two monitors I only have the one attached to the laptop :-)
I have two propper Ubuntu installations on two different laptops that I upgraded to Precise.
What is the expected bahaviour of the Software Center because Ubuntu seems the same on my two machines?

[jhfhlkjlj (fdsuufijjejejejej-deactivatedaccount)]

Do all of the machines you are using have the unity staging PPA installed? There's a good chance that that is the issue, then.

[Joschi Poschi (joschiposchi)]

I had this problem before using the Unity staging PPA and before moving to Precise.
I believe now the windows behave like there was no panel and are therefore moved.

[Joschi Poschi (joschiposchi)]

Seems to be a more general problem of window placement/restoration because I got the same result of moved windows when I tried the 'minimize on launcher' patch (http://www.webupd8.org/2012/03/unity-with-minimize-on-click-patch.html).

[Joschi Poschi (joschiposchi)]

I had to deactivade the additional animation addons from the compiz-plugins-extra package because it caused unity to crash and after doing so the strange window restoration is gone. So maybe the bug is related to this package (but I'm wondering because for mini/maximize I set "Zoom" which is from the not from that package).

[Joschi Poschi (joschiposchi)]

Meanwhile I made a clean install of 12.04 and I'm still having this problem. Also I can say that it isn't the compiz-plugins-extra package as I didn't install it. So I guess it's something wrong with compiz in general (window placement/recovery as I said before).
Both of my laptops are Lenovo machines with onboard Intel graphics, maybe that helps.

[jhfhlkjlj (fdsuufijjejejejej-deactivatedaccount)]

Unfortunately, we're going to have to wait for someone to be able to reproduce/pinpoint this bug. I have not been able to reproduce this at all.

[dino99 (9d9)]

That version has reached EOL since a while, so it will not receive update. If that issue still exist, report again using ubuntu-bug.
