Bug Description

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.

Thank you for your bug report, I guess you use a small screen resolution which makes the control panel use the screen size, that doesn't happen on a desktop configuration. Confirming the issue, it's suboptimal but I'm not sure there is a good way around it (you can middle click on a slider position to change to it which should avoid the feedback loop issue though)

Changed in gnome-control-center (Ubuntu):
importance: Undecided → Low
