nouveau problem?

[Ed Greshko]

Hi,

I've just installed F15 on a system previously running F11.  The video 
card is a nVidia GeForce GT 230 and I was running the nVidia drivers. 
Now, I'm trying out the nouveau driver.

It seems to mostly work.  But, there is an issue which may be due to 
nouveau.

When I mouse over an application on the panel a box pops up with the 
name of the application and for a second a square within the box shows 
the running window.

Also, if I move my mouse to the upper left corner, all desktops should 
be displayed.  However, they are a bunch of grey blobs.

Is anyone seeing this?
