Default Screen flashes once every 430 seconds...

Any clues on what may be causing this?

I am running Fedora Core 2 on a system with a Geforce Go5600. Everything works perfectly (drivers, GLX, X-windows). But every seven minutes or so, the display flashes for one frame with alternating rows of solid white and dotted white lines. It's as if some process is rewriting the video timing registers every seven minutes and 10 seconds (I've timed it!).

This happens regardless of whether a full-screen OpenGL application is running (bzflag) or if the X-server is idle.

Cheer,
MichaelR
