Tested the downgrade: Had no issues there Just 3.1.0
It starts with artefacts underneath the icons (grey bars where the shadow is supposed to be) Then, when 2 or 3 icons have these artefacts (mostly file folders and mail apps) on dismount of a disk the dock hangs. I can only reproduce the hang when dismounting drives. On my testmachine (which runs mostly unobserved) I cannot isolate the cause -- You received this bug notification because you are a member of Cairo- Dock Devs, which is subscribed to cairo-dock in Ubuntu. https://bugs.launchpad.net/bugs/1069854 Title: GLX-dock hangs regularly since update to 12.10 Status in “cairo-dock” package in Ubuntu: Incomplete Bug description: The dock regularly hangs (accepts no input, does not react to mouse over events) and does not let itself stop by right-clicking the background. Kill and restart are the only options to get it working again. As the launcher does not work properly as well this is a pretty serious limitation in every day work. Boys (and girls) what did you think when sending this version (12.10) out. It's the worst I ever experienced.
