application window opens behind other windows

[Andre Inglis]

Binary package hint: xorg

Here are the exact steps I take for the bug to appear:

1. Open Firefox (or any other program that takes up about 3/4 of the screen)
2. Click on the Firefox window (you need to do this for the bug to happen)
3. Click the Ubuntu icon in the upper left hand side of the screen to open the Applications Window

The Applications window appears behind the Firefox window. I expect the Applications window to appear on top of it.

Are you certain this is not a unity bug? I can't reproduce the issue using your steps.

[Andre Inglis (andre-inglis)]

I'm not sure what to file it under Bryce.

[Bryce Harrington (bryce)]

Ok no prob. I think maybe it is a unity issue. See if you can reproduce it with the classic desktop, with desktop effects turned on.

Also, is it just the Applications window that shows this behavior, or is it similar for any popup dialog that should overlay another window?

[Andre Inglis (andre-inglis)]

I tried this on two different laptops (Samsung and HP) on the livecd and both have the same bug. I did a full install on my Samsung and the bug was still there, but I did not get a chance to try the classic desktop. After a reset the laptop booted into a purple screen and froze. Subsequent resets did not alleviate the problem.

Also, I was not able to activate the effects in the 'Change Background' menu. Whenever I tried to do this on the livecd the effects automatically turned off (or at least the indicator in 'change background' showed them as turned off) on both laptops. No error message showing. Possible bug?

I attempted to reproduce this bug with other applications but they worked fine. Only the 'applications' window seems to do it.

[Bryce Harrington (bryce)]

Okay, thanks for the additional testing. It's sounding more like a unity bug, if it can only be reproduced with the Applications menu. I'll refile this to unity.

For the other issues you ran into, the purple screen + freeze sounds like a kernel drm bug. That class of bug tends to be very hard to diagnose, unless apport is able to automatically catch it. There are various workarounds depending on your hardware, but I'd suggest raising the issue on http://askubuntu.com for that.

The trouble activating effects could be a compiz bug, but I'm not sure. There are established procedures for diagnosing that class of problem. If you want to chase that bug, I'd recommend opening a bug report against compiz if you want to investigate that.

[Didier Roche-Tolomelli (didrocks)]

Right, it's rather a compiz bug, I can't reproduce it though.

[Pedro Villavicencio (pedro)]

Thanks for your bug report. Is this still an issue with the latest release of Ubuntu the Natty Narwhal? May you please check and comment back? Thanks in advance!.
