Extreme IO using libre/openoffice
Submitted by dE

Since the last few days and in many places, I've been wandering around posting this -
"I've been using KDE (QT) build of Openoffice on Gentoo and suddenly came across this strange problem which also persist with GTK openoffice and even Libreoffice.
It appears Openoffice takes too much disk I/O when drawing toolbars, it takes 2 minutes to cold start OOo, and in the mean time the whole system is unusable (I can hardly move the mouse) + the kernel hangs when I doing some other I/O intensive tasks while OOo is loading, and sometimes it hangs even if I'm nothing doing anything.
Since Base doesn't have many toolbars by default, it opens OK, but other things are just horrible.
Most important fact is that all this happens when composting is enabled with Kwin.
Also I've seen, this problem persists only if Kwin render method is OpenGL, if it's XRender, the problem's solved."
As bug reports or in forms.
The problem appears to come from the latest mesa (May 16th 2011), downgrading to 7.10.2 solves the problem.
