HUD: The selection always returns to the first item whenever menus are updated

can you please make a video of the issue you see and attach it to the bug.

Uh, oh, that's nasty :/

I wonder if that have something to do with your locale. tried with english? maybe guest session?

I have this bug as well when I'm logged in as my normal user, but it does not happen when I'm in a guest session.
My normal user has English interface but Hebrew keyboard layout is also enabled - but the bug happens when the active layout is US.
Here's the output of "export | grep LANG ", for my normal user in case it's relevant:

declare -x LANG="en_US.UTF-8"
declare -x LANGUAGE="en_US:en"

same problem but slightly different reaction.

bug appears with the guest session but it does stop and restart meaning:
log in as guest (other account still logged in)
HUD > write > select with arrow down
after a a few tries, the selection is working (not coming back to the first entry) then all of a sudden it defaults to first one again and so on.

french keyboard. I tried with a US layout, same.

LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

my OS is an upgrade from 10.10 to 12.04.

Just figured out that it may come form the upgrade.

Indeed, I do not have any problem with a brand new user.

Yes this bug is driving me crazy... also reported here => #966632

Here is a video of my issue.

I also do not have this in the Guest Account. Tried different KB languages etc, does not fix the main account.

I have found the issue, give me two seconds.

The HUD navigation response is directly correlated to what is running in the indicator bar.

I had the following running:

Indicator-Mutliload
Psensor
PS3 Media Server
Indicator Weather

I quit Indicator Multiload and when arrowed down in them menu the selection remained for a few seconds before moving back up. It appears that when the added indicators refresh the force the HUD to refresh back the top position.

I deleted the rest and it fixed itself. I can now move through the menu bar without an issue.

I will re-apply the indicators and see what I can use and what I can't. Google-Music-Manager so far is running and is not causing a issue.

Psensor and Indicator-Multiload both cause the issue.

PS3 Media Server and Weather-Indicator do NOT effect the HUD.

The selection returns to top whenever any item in whole menu structure is updated. So it depends on refresh interval of indicators like indicator-mutliload.

Same problem.
I have Indicator multiload active.

For Psensor at least, my guess is that it is due to menu items which are refreshed periodicaly.

Until I found a fix for this issue, you can increase the graph refresh duration (which is used also as indicator refresh period), it will limit the impact.

I can confirm that after disabling indicator-multiload, the problem no longer occurs. So it's related to the refresh duration as everyone else mentions already.

Unity should probably freeze the model it's using when the ui is open to avoid those issues, raising to high, it's less frequent without indicators like multiload but still nm applet and others do frequent updates and that's a bad user experience

I did not find any way to workaround at application level (for Psensor) this issue.
My idea was to update only once the menu label when the application indicator menu is popup but I did not find any gtk signals for this purpose and the menu widget is alway flagged as visible even when not...

two possible fixes, both in unity:

1) keep the cursor in the same physical position when the list updates

2) look at the item key (which is just a 64bit integer these days) of the item that was selected before refreshing the list and search for that item in the new list, causing it to be the new highlighted item

one more possible fix in the backend (but will only help with some cases):

scan the old list and the new list for being equal and don't send updates in that case

Solved!

HUD works... but there is still an "interference" with Indicator multiload (icon and command).
But it is usable.

Have you noticed that?

Here an image.

@palimmo: could you open a new bug report? is that only happening when using multiload?

No.. it happens also with VLC, weather-indicator, Skype, GoldenDict, gm-notify.. probably every app that shows something in the notification area.
Yes.. I open a new bug.

Bug opened.
