Filtered list rendered incorrectly after refresh

[Reinis Zumbergs]

Xubuntu 14.04 amd64 upgraded from 13.10

synaptic 0.81.1

1) Open Synaptic
2) (with apt-xapian-index) Search for something in Quick filter
3) Choose a package and mark it for changed status
4) List refreshes and item count is the same but these are "phantom" items from the top of this same listing, but as if it was not filtered
5) Move cursor over the list and the real items are revealed

 - Intel Graphics card
 - Bug reproducible both when Xfwm compositing is enabled and disabled

Status changed to 'Confirmed' because the bug affects multiple users.

[John Littleton (jelittleton)]

This bug also occurs in ubuntu 14.04 from a clean install (no upgrade).

- Intel i5 3570k with integrated graphics

[Phil Wright (jozubiso)]

Also occurs on clean install of Xubuntu 14.04 x64 on 2 (very) different computers.

[M4he (mahe)]

I can confirm this on an Intel HD 4000 using a MacBook Air running a clean install of the latest Xubuntu 14.04.

I just tried switching to the older UXA acceleration backend instead of SNA but the issue persists. It's at least unrelated to the Intel driver's acceleration method. (SNA caused graphics/redraw errors on GTK for me in the past, that's why I tried it)

I've hacked in this fix for it - this forces the tree view to refresh after a package selection change. No idea of the side effects, but "works for me". It still has a little visual flicker after selection change but at least there are no more phantom entries.

Will a fix be provided (as indicated in comment #6) - e.g. via a PPA?
I am willing to test.

[Richard Quirk (quirky)]

I'm not an Ubuntu developer, just some random guy on the internet. But here you go https://launchpad.net/~quirky/+archive/synaptic

[JMB (jmb-tux)]

Thanks for the PPA - it works for me.
Ubuntu should provide this or a similar patch via standard repositories ... if LTS should mean something.

[Richard Quirk (quirky)]

Heh, I wouldn't hold your breath JMB. LTS is usually only for security fixes, and this is merely cosmetic. Also synaptic doesn't have the little Ubuntu symbol by it, which means it is "unsupported" or something.

They do make bug fixes in LTS releases, too, but I'm not sure if this will
meet the criteria or not. The lack of Ubuntu symbol means that the
package is community-supported, ie, not supported by Canonical.

Sorry for the trouble this bug causes.

It is fixed in utopic with the coming sync of synaptic 0.81.2. I uploaded a SRU with the fix, see the debian bugreport for the (small) patch.

[Scott Kitterman (kitterman)]

Hello Reinis, or anyone else affected,

Accepted synaptic into trusty-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/synaptic/0.81.1ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[Scott Talbert (swt-techie)]

Tested synaptic 0.81.1ubuntu1 from trusty-proposed - the bug is resolved in this version.

[JMB (jmb-tux)]

I would have liked to test the new version - it seems to be no longer available
(if I did not enter something wrong):

[code]
sudo vi /etc/apt/sources.list
  ## SYNAPTIC error with displaying old lines after selection:
 deb http://archive.ubuntu.com/ubuntu/ trusty-proposed restricted main multiverse universe
 # see: /etc/apt/preferences to avoid automatic updates from proposed!
 # - installed via: sudo apt-get install synaptic/trusty-proposed

sudo vi /etc/apt/preferences
  Package: *
  Pin: release a=trusty-proposed
  Pin-Priority: 400

sudo apt-get install synaptic/trusty-proposed
  Reading package lists... Done
  Building dependency tree
  Reading state information... Done
  E: Release 'trusty-proposed' for 'synaptic' was not found
[/code]

Is there a possibility to test the new version myself?

When will the new version enter standard repositories?

Thanks in advance for the information!

[Mateusz Stachowski (stachowski-mateusz)]

I also confirm that the Synaptic from trusty-proposed fixes this bug.

[Reinis Zumbergs (reinis-zumbergs)]

Hi Scott,
I confirm that the issue is solved now. Thanks :)

I think it should still be there. Did you do a 'sudo apt-get update'
after you edited /etc/apt/sources.list?

> When will the new version enter standard repositories?

My guess would be probably in a day or two.

The verification of the Stable Release Update for synaptic has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.
