Comment 12 for bug 985202

I don't know, but they seem to have also serious performance problems on 12.04 which they at least know about:

From my POV it is a shame that they list Ubuntu 12.04 as "supported" on their downloads page, although this serious performance bug and this kwin issue here exists. Sometimes I am really wondering what type of testing they do before making such announcements in their download section. I have lost a bunch of time with downgrading back to 10.04 because of these two issues.
