launcher is not refreshed after user session switch

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

This affects me as well running Nvidia version current-updates. Ubuntu 12.04

Also affected by this bug, the first time I tried to reproduce the launcher was not drawn at all until I moved my mouse over the area. I then switched to the guest account and back and the system locked up and I had to hard reset. Upon trying it again I got the ariefacts as described above until I moved my mouse into the launcher area again.

I suspect this will be fixed by: lp:~vanvugt/unity/regionalDamage
So assigning to myself unless proven otherwise.

Fix committed into lp:unity at revision 2470

Thanks for the fix.

I tried to build the latest Unity and Nux from source and play with it under Ubuntu 12.04, this issue has been fixed. However, I found other issue.

As screenshot I attached, If I start to drag many files, the Launcher and Panel will disappear, until I release my mouse, they will be back.

My system: Ubuntu 12.04 with source compiled Nux and Unity, nVIDIA card.

Ding, would you please open a separate bug for this? The unity devs are considering the original issue to be fixed on their side. Also, please include the graphics device and drivers you're using in the report.

This bug was fixed in the package unity - 6.0.0-0ubuntu1

Quick quesiton, does targeting SRU-2 mean it's going to get a stable release update in precies?

I hope so. This work has been done targeting precise, and we are just
waiting for SRU 2.

Hello Francis, or anyone else affected,

Accepted unity into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/unity/5.16.0-0ubuntu1 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 change the bug tag from verification-needed to verification-done. If it does not, 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!

Hello!

I enabled proposed like told above and did "sudo apt-get -t precise-proposed install unity".
After logging off all users I tested the new package.

Result: Screen refresh is now WORKING! I experienced no other problems until now.
Thanks very much!

installed unity 5.16.0 and problem with refresh of launcher seems fixed, but other applications still have redraw problems, see attachment.

I tried this new unity version (5.16.0-0ubuntu1), and it works! I cannot reproduce the bug now.

This bug was fixed in the package unity - 5.16.0-0ubuntu1
