I recently bought a Dell Inspiron 1525 to run Intrepid. So far I'm really happy, however with Normal or Extra visual effects, I often notice "static" interference across the screen when opening new windows. The problem never lasts: once the window is open there's no problem.

I have 3GB of RAM, 15.4" WXGA display with True Life with Graphic Intel Integrated GMA X3100.

Does anyone have any solutions other than selecting None for visual effects, or indeed any explanation for what is happening?

Thx.
