Hi,
After some digging into the problem it appears that problem resides in xorg driver, in EXA engine to be more specific.
I've changed EXA to XAA and problem disappeared. There are another annoying issue with screen flickering every few minutes/tens of seconds. But I am giving a try to new driver/drm (2.5 from https://launchpad.net/~thjaeger/+archive) until now it's ok.

BTW: I am moved to Gnome after more then 8 years with KDE, and that solved another fewr performance/visualisation problems.
