This is very likely a problem with the video drivers not handling ARGB visuals correctly.

I thought about it and posted this idea at http://forum.kde.org/viewtopic.php?f=67&t=93320 and I was advised to post my problem here. This problem doesn't appear in gnome and that's why I think that this is KDE's problem.
clearly a driver bug. I recommend to update to Mesa 7.10 (assuming that it is a free driver), disable graphicssystem raster in Qt (in case of Intel hardware).
I've updated my Mesa. Now it seems to be OK. Thx.
