I can also confirm this on multiple computers.

Running both fglrx and nvidia-new drivers, using one bottom panel only - running Desktop Effects with "Extra Effects" enabled.

Panel shows when clicked on the area... Perhaps the load order needs to be changed or compiz load delayed?

Same problem for me. Happens with both top and bottom panels. Started in the past week or so.

comfirmed....

but when you restart compiz , sometime it'll be ok with the panel...

I tried changing the load order (making sure gnome-panel was loaded after nautilus, as suggested somewhere online), but that didn't help. Gnome-panel loads fine, but it seems that when compiz loads it just turns invisible.

I managed to get my panel back to a visible stat by turning of "clone output" in ccsm. Not sure how or why this works, but I'm glad it does for me :) Hope this can help some of you out there.

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