I had this bug earlier, that I thought was fixed with overlay-scrollbar blacklists, but it happens again today.
Steps to reproduce :
- disable swap (otherwise you’ll get an endlessly swapping multi-gigabyte Xorg)
- start vlc
- click the show playlist button
Running an up to date oneiric with fglrx.
