I'm pretty sure this is a FGLRX related issue because I only started having this issue after installing a Radeon 6870, and therefore switching to the FGLRX driver. I previously used Natty with an NVidia 9600 GT and the Nvidia binary from the website with mipmapping enabled, with no problems.
However, I would like to confirm the same issues have been happening to me when using any plugin with mipmapping enabled. This means both application switchers, as well as the Expo plugin. I don't think this is a terribly important bug because none of the plugins have mipmapping enabled by default (right? I dunno actually...) but having mipmapping disabled has a huge impact on compiz's visual quailty, so it is definitely important that this gets fixed. driver info: $ fglrxinfo display: :0 screen: 0 OpenGL vendor string: ATI Technologies Inc.
