This also happens to me when starting VLC. It also happens when I drag the sheet tabs in OpenOffice Calc along.
Using Ubuntu 10.10 64-bit, nvidia GeForce 9800 GT (nvidia driver version 260.19.06) and with 2 displays running xinerama.

It doesn't happen anymore after disabling xinarama

Most likely an xorg issue, so moving for triage.
