Refresh problems with ardour

Hi,

I just installed ardour with the Fedora 11 softward add/remove tool, but it doesn’t look right. I get a checkerboard of grey squares everywhere! Also, the window insists on being just a little bigger than my screen. Does anyone else have this problem?

Thanks, and all the best,

Tony
