Hm. I will not dispute this, I don't use wine, and up till now I used
only QT/GTK based apps, which don't seem to have the problem you mention.
Qt uses it's own routines to draw, if I'm correct, probably this is why 
they haven't noticed/fixed this before the release...

Other than that, I've used Kubuntu 9.04 to finally convince some people
to switch to Linux, and I'm now definitely dropping OpenSUSE in favour
of Kubuntu, so you won't hear me complain about it (yet) :-)
