Public bug reported: This is in 12.04 Precise Pangolin. I got to the "Appearance" page in "System Settings" (which seems to be really named gnome-control-center), while looking to reset the launcher auto-hide behaviour back to the way it was in Ocelot, and found this tool for adjusting the size of the launcher icons. Hmm..what happens when I play with this knob...
When the launcher is visible, adjusting the launcher icon size causes the window containing the icon-adjustment tool to be resized, which causes the position on the screen for various launcher icon sizes to change - this causes the launcher icon size to be further adjusted, which causes the icon-adjustment tool to be resized, which causes the position on the screen for various launcher icon sizes to change - this causes the launcher icon size to be further adjusted.... If you wait a while, the oscillation eventually damps down, but the feedback effect makes the adjustment very touchy to perform. When the launcher auto-hide is turned on, there is no oscillation, because the launcher is hidden, but that also means that there's no visual feedback (only numeric) as to what size the launcher icon size gets set to. ** Affects: gnome-control-center (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990161 Title: launcher-icon-size adjustment very wonky when launcher is visible To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/990161/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
