Ok, as the subject suggests, there probably is a name for what I'll be referring to, but I'm having a blonde moment right now!
I've just upgraded to Felicia x64, which I'm liking lots
(usual Flash issues, but there we are), and got all the Compiz bits and pieces set up. Then I noticed that when the cursor is hovering over something, e.g. an icon on the taskbar or MintMenu (or the list of smilies on my right as I'm typing this!), the block that flashes up with a description etc is solid black. Disabling Compiz doesn't seem to do anything. I'm also using Emerald.
Any ideas? Or at least the name for the description-thing that pops up?
