Launching Gimp always makes the Ubuntu button go blue

[Matthew Paul Thomas]

Since Unity 3.8.6-0ubuntu1 an auto-hidden Launcher indicates an application focus request by displaying a small (blue) triangle in the top-left of the screen (added per bug #755286). The indicator is intended to show only when an application specifically requires attention. To reproduce:

  1. Launch the Gimp, and wait. (Alt-F2 gimp [enter])

What happens: The Ubuntu button goes blue.
What should happen: The Ubuntu button does not go blue.

Problem occurs with:
* unity 3.8.2-0ubuntu1, Ubuntu Natty daily 20110404
* unity 3.8.8-0ubuntu2, Ubuntu Natty beta 2

Note that this issue does not occur with either the Unity-2D or Classic GNOME2 Panel+Metacity environment so it likely indicative of a bug in Compiz/Unity. The correct function in GNOME2 Panel can be confirmed by loading Gimp as above and observing that:

  * In the Ubuntu Classic session (no taskbar button goes bold)

the issue there is not an unity one, the claim for attention is not specific to unity, it's either a compiz or a gimp issue, it's likely a dialog get denied focus on start and triggers it

Does not affect Unity 2D.

[Andreas Grois (soulsource)]

Yup, it's because one of the Gimp-Windows wants to get the focus. Click on each of them and the Unity-Button is normal again. I'm notsure, but I think the same behaviour is observed with the gnome-panel taskbar.

This is more likely Compiz/Unity bug, it happens to me with Empathy. See bug 762877.

This bug does not affect the Classic session, so I don't see how it can be a bug in Gimp. Moved back to Unity.

> This bug does not affect the Classic session

How did you try? I can't confirm that there, using compiz with gnome-panel and not unity I get one of the toolboxes title displayed in bold which is the unity equivalent of the blue corner, it's not doing any effect on it though

[Matthew Paul Thomas (mpt)]

I tried by logging out, logging in to the Classic session, and following the steps to reproduce described in the bug description. Is there some other way I should do it?

[Sebastien Bacher (seb128)]

can you take a screenshot of your GNOME session after starting gimp?

seems similar to bug #755697
