Comment 3 for bug 778407

this affects me as well. every time i open monodevelop, the panels disappear, sometimes straight away, sometimes when i close monodevelop. monodevelop seems to cast an edge shadow over the panels in a way that other windows dont, maybe this is related.

also possibly related is the fact that my panels are set to be slightly transparent, which i don't want to give up. i would be interested to know if the original poster has transparent panels?

the panels are still there, but invisible. i can still open the menu and open the terminal. i type

killall gnome-panel

and the panels restart, and it's back to normal.

im using 10.04 lucid, with metacity not compiz. however, i have checked the "compositing manager" box in the metacity settings in gconf-editor so that i get true transparency in my terminal which also matters to me.

hopefully some or all of this is useful.
