KDE 4 has a lot of desktop effects and defaults to using a OpenGL backend for
the effects. For Intel chipsets I would personally recommend using the XRender
backend. I use this at work and have been pleasantly surprised with how well
the Intel driver and chipset handles it. You can change backend under System
Settings -> Desktop -> Desktop Effects -> Advanced. You can also disable them
for a KDE 3.5 like experience.
