Steve Magoun (smagoun) wrote on 2012-01-12: Unity launcher corruption on resume from suspend

The unity launcher is reliably corrupted upon resume from suspend with some (all?) NVidia hardware with the proprietary NVidia driver. All other visual elements seem to draw correctly, it's just the unity launcher that has this problem. The launcher looks fine after it redraws (for example, if you mouse over it).

The problem is not reproducible on Intel or AMD graphics hardware, and I'm told (by Ted Gould) that it doesn't affect the nouveau driver. I have not tested the nouveau driver myself.

This problem been reported several times in the comments of bug 676166, I'm filing this separate bug for clarity since 676166 is overloaded.

To reproduce:
1) Suspend
2) Resume
2a) login, if necessary. Note that the login screen (lightdm) displays properly
3) Notice the corrupted launcher
4) Mouse over the launcher; the launcher redraws and the corruption goes away

The problem affects 11.10, and is not fixed by upgrading to more recent unity, compiz, or nvidia drivers from oneiric-updates or even the most recent SRU candidates not yet in oneiric-proposed. Currently I have the following installed and the problem still exists:

Unity SRU candidate (not yet in -proposed):
ii unity 4.28.0-0ubuntu1~ppa1 Interface designed for efficiency of space and interaction.

Compiz SRU candidate (not yet in -proposed):
ii compiz 1:0.9.6+bzr20110929-0ubuntu6.1~oneiric1 OpenGL window and compositing manager
ii compiz-core 1:0.9.6+bzr20110929-0ubuntu6.1~oneiric1 OpenGL window and compositing manager

Hardware is a MacbookPro 3,1 w/ NVidia 8600M GT. I'm using the amd64 build of 11.10.
